Assessment of non-linear rock strength parameters for the estimation of pipe-jacking forces. Part 2. Numerical modeling
No full textIn the earlier companion paper (Ong and Choo, 2018), direct shear tests were performed on reconstituted tunneling rock spoils for the development of equivalent tangential cohesion, c't,p and friction angle, ϕ't,p. These equivalent rock strength parameters were used in assessing jacking forces, which were measured from three pipe-jacking drives negotiating the highly weathered lithologies from the Tuang Formation, Malaysia. The measured jacking forces were back-analyzed, leading to the development of frictional coefficient, μavg and the vertical stress at the tunnel crown, σEV. In this paper, the reliability of using the parameters, c't,p, ϕ't,p, μavg and σEV was assessed through the use of three-dimensional finite element modeling of the studied pipe-jacking drives. The peak tangential strength parameters, c't,p and ϕ't,p were applied to the modeled rock mass and the strength parameters of the pipe-rock interface were developed from μavg. Arching ratios were developed from σEV, which were subsequently used for post-analysis assessment of the results from numerical modeling. There was sound agreement between the resulting pipe-rock interface shear stresses, τ1 and reaction loads, ΣFy from the numerical analysis against the field measured jacking forces, thus demonstrating the reliability of the use of developed equivalent rock strength parameters, c't,p, ϕ't,p, μavg and σEV in the assessment of pipe-jacking forces through highly weathered lithologies.Full Tex
CS Seminar Videos
No full textMain site for our project can be found at this URL: http://vtechworks.lib.vt.edu/handle/10919/19036. From here you can find videos of all the CS seminars and distinguished lectures given this semester. Each video has its own abstract and description. The files attached in this section are a final report in both raw Word Document and archival PDF formats and a presentation in both raw Powerpoint and archival PDF formats.Computer Science seminars are a very educational and interesting aspect that the CS department offers to the students attending the university. There are numerous occasions in which many students are not able to attend the seminars. Taking this into consideration our group was responsible for the digital video recording and editing of the CS Seminar talks. This allows for students to re-watch a seminar if they can’t remember all the information. Each seminar is held on Friday at 11:15am in Torg 2150. We recorded each CS Seminar, edited it, and posted it to the VTechWorks website that is located at this link: http://vtechworks.lib.vt.edu/handle/10919/19036. This project has been an ongoing project as seminars and talks are held every semester. The main purpose, along with what was described above, is to attract more people to Computer Science and support the Computer Science department based on research discussed in the seminars. Having these seminars uploaded onto a website that is easily accessible will generate interest in the computer science field as well as give people already in the field something potentially new and interesting to think about
Interpretation of Pressuremeter Test in Fractured and Weathered Phyllite for Back-Analysis of Pipe Jacking Forces
No full textCharacterisation of highly fractured and weathered rock masses within the young Tuang Formation in Sarawak, Malaysia is challenging, mainly due to the difficulties in extracting intact samples for conventional rock testing. Pressuremeter test was used as a viable alternative since it is performed in-situ, hence eliminating the need for sample extraction. A methodology was developed to interpret pressuremeter test results in highly fractured and weathered phyllite using an analytical approach, from which useful strength and stiffness parameters can be obtained. The interpretation method was based on the fundamental theory of cylindrical cavity expansion, which was originally established for soils. The results of the interpretation were in terms of commonly known Mohr–Coulomb strength parameters, which were subsequently used for assessment of frictional pipe jacking forces through back-analysis method. The results of the back-analysis showed the reliability of the developed methodology in analysing pressuremeter test results within highly fractured and weathered phyllite.Full Tex

Motifs in Woodblock Prints and the Ritual of Ong Tao ： －With Emphasis on Ong Tao Woodblock Prints in Sinh Village－
No full textThis paper will focus on motifs in Ong Tao woodblock prints and identify their characteristics based on interviews with their producers and comparisons of these artworks. In each household of the Kinh ethnic group in Vietnam, the yearend ritual to send the Kitchen God called Ong Tao to heaven takes place on December 23. In the Hue region, this ritual means placing an Ong Tao statue that has been enshrined in an alter for the past year in a shrine or under a sacred tree to aid the god’s rise to heaven. It also involves burning Ong Tao woodblock prints produced in Sinh, one of the small villages in Thua Thien Hue province. All traditional woodblock prints from the village are produced for ritual ceremonies, and the Ong Tao prints are no exception. These pieces of art are exclusively used in the Hue region, and are not distributed anywhere else. There are two other types of Vietnamese folk woodblock prints depicting Ong Tao: Dong Ho woodcut paintings and French artist Henri Oger’s works from the early 1900s that capture daily life and the art of living in northern Vietnam. These prints are different from those from Sinh village in their printing techniques and motifs. The author conducted interviews with artists currently creating Ong Tao woodblock prints in the village, with the aims of identifying the characteristics of the artworks based on their motifs and exploring why the motifs in these woodblock prints are different from those depicted in Dong Ho woodcut paintings and works by Henri Oger. An analysis of the motifs should confirm that Ong Tao woodblock prints are produced for the ritual. Furthermore, the study will propose that the unique features of these prints from Sinh village can be attributed to the capital of the Nguyen Dynasty being located in the Hue region.Departmental Bulletin Paper2014年度奨励研究 成果論文論文departmental bulletin pape
Determination of jacking forces based on highly weathered non-linear 'soft rock' strength parameters considering arching
No full textAs microtunnelling by pipe-jacking continues to remain an efficient method of constructing buried infrastructure in densely populated urban areas, it is paramount to understand the effects of geology on pipe-jacking forces. There continues to be a knowledge gap when understanding the accrual of frictional jacking forces for drives negotiating geological rock formations, particularly highly erratic and highly weathered geology. This paper presents a methodology for understanding the effects of highly weathered geology on pipe-jacking forces. This method was developed during the construction of a 7.7 km long trunk sewer network at depths of up to 30 m below the central business district of Kuching city, Sarawak, Malaysia. At such depths, the encountered lithologies from the Tuang Formation predominantly presented RQD values of 0%, which created difficulties when extracting rock samples for strength characterization. Therefore, excavated tunnelling rock spoils were instead collected and subjected to direct shear testing. The reconstituted tunnelling rock spoils demonstrated behaviour, characteristic of the nonlinear power law. For application to assessment of jacking forces, the developed peak tangential strength parameters, c't,p and ϕ't,p were found to have been closely related to the mineralogy of the respective lithological units, which subsequently affected the lubrication and accrual of jacking forces. This was explained through back-analysed values of pipe-rock frictional coefficient, μavg and vertical stresses at the pipe crown, σEV. These back-analyzed parameters provided insight into the effectiveness of lubrication efforts and the development of arching, which were closely related to the traversed lithologies. It was found that the highly weathered geology was able to arch, suggesting that the highly weathered and discontinuous 'soft rock' masses demonstrated soil-like behaviour.Full Tex
