MODELLAZIONE DEL COMPORTAMENTO TERMOMECCANICO DELLA DIGA DI PONTE COLA
No full textIn Italia, le grandi dighe presentano un’età media superiore ai 65 anni, con inevitabili criticità legate all’invecchiamento e alla crescente severità delle condizioni ambientali (ITCOLD, 2018). Diventa pertanto essenziale garantirne l’operatività attraverso interventi di manutenzione e l’adozione di metodi di monitoraggio avanzati, supportati dalla modellazione numerica. L’obiettivo del presente lavoro consiste nell’interpretazione del comportamento di una grande diga a doppio arco in calcestruzzo attraverso l’interpretazione di dati di monitoraggio e la successiva creazione di un modello FEM. Il caso studio è quello della diga di Ponte Cola situata a Navazzo di Gargnano (BS). L’analisi è basata su dati di monitoraggio periodici e continui e ha previsto la creazione di un modello FEM attraverso l’utilizzo del software Midas FEA NX, calibrato in base alle risposte misurate, con l’obiettivo di cogliere le principali dinamiche termiche e meccaniche dell’opera. Il modello calibrato fornisce risposte coerenti con le misure acquisite dai sensori, permettendo di comprendere il comportamento strutturale anche dove l’interpretazione risulta complessa a causa della geometria e della distribuzione dei carichi applicati

MONITORAGGIO MULTISENSORE DELLA DIGA DI PONTE COLA: CONFRONTO TRA TECNICHE TRADIZIONALI E SENSORI DISTRIBUITI IN FIBRA OTTICA
No full textIl monitoraggio strutturale delle dighe sta assumendo un ruolo sempre più centrale, a causa dell’invecchiamento delle infrastrutture esistenti e dell’accelerazione dei fenomeni di degrado indotta dai cambiamenti climatici e ambientali (Perera et al., 2021; Sivasuriyan et al., 2022). A partire dagli anni Settanta, l’introduzione di strumenti sempre più precisi e automatizzati ha consentito di migliorare la conoscenza dello stato di salute delle opere, riducendo al contempo l’intervento umano e il rischio di errore (Adamo et al., 2020). Tra le tecnologie più recenti si collocano i sensori distribuiti in fibra ottica (DFOS), che offrono numerosi vantaggi applicativi nel monitoraggio geotecnico e civile. Tuttavia, la letteratura scientifica presenta ancora pochi casi studio incentrati sulle dighe che ne dimostrino concretamente l’efficacia e l’affidabilità.
Il presente lavoro si concentra sul caso studio della diga in calcestruzzo di Ponte Cola (Brescia, Italia), dotata di un ampio sistema di monitoraggio tradizionale, al quale è stato affiancato un sistema DFOS sperimentale. L’obiettivo è validare l’utilizzo della fibra ottica per il monitoraggio strutturale e contribuire allo sviluppo di casi applicativi di riferimento. I dati acquisiti dai sensori convenzionali sono stati elaborati per descrivere il comportamento della struttura in risposta alle variazioni termiche stagionali e confrontati con quelli ottenuti dal sistema DFOS. I risultati mostrano una buona coerenza tra le misure, con scarti medi massimi dell’ordine di 1 °C per la temperatura e di 1 mm per le deformazioni. Il sistema DFOS, a differenza degli strumenti puntuali, fornisce inoltre una misura distribuita lungo l’intera estensione della fibra, permettendo una lettura continua delle sollecitazioni e una copertura più ampia della struttura. Esso rappresenta quindi una valida integrazione ai metodi di monitoraggio esistenti
Landslide Risk Management in Practice: Phased Mitigation Using the Observational Method
No full textLandslide risk management typically involves an initial assessment to characterize the phenomenon and a subsequent phase to design and implement safety measures. However, financial constraints and technical challenges often require a phased approach to optimize resource allocation. In such cases, the observational method provides a flexible approach, allowing for phased implementation of measures while monitoring their effectiveness over time. In this study we applied this strategy to the "Paradisi" landslide (Belluno, Italy), a rotational slide at the interface between moraine debris and the Belluno Flysch formation.The 115x200 m landslideinvolves nearly 200,000 m3. Predisposing factors include poor geotechnical properties, high water content at the moraine-Flysch interface, and steep gradients, while intense winter precipitation triggers rapid mudflows along a central watercourse.Initial interventions addressed critical instabilities through slope reprofiling andshallow and medium-deep drainage systems. At the same time, monitoring systems - inclinometers and piezometers - tracked the slope behaviour. Subsequently, smart self-drilling composite anchors with optical fiber instrumentation were installed to stabilize the slope. Finally, the landslide toe was reinforced with a row of gabions spanning almost the entire width of the landslide. Drone-based photogrammetric periodic surveys complemented the monitoring efforts.This phased strategy allowed for iterative refinements, with each intervention evaluated based on observed residual movements and site conditions. The observational approach ensured that limited resources were effectively utilized.This strategy was applied not only to adaptively guide the phased course of action but also as a long-term framework to monitor future landslide evolution. This approach aims to assess the potential need for further risk mitigation phases, ensuring sustainable resource allocation and long-term site safety. The case study highlights the importance of integrating phased strategies with robust monitoring systems to optimize landslide risk management under resource constraints

Endowment of the Faithful with the Sciences of the Prophet’s Hadith
No full textمختصر مبسَّط في علوم الحديث، موجَّهٌ إلى طلاب جامعة عمر المختار، توخَّى فيه مؤلِّفه بساطة الأسلوب، وسهولة العبارة، ممهِّدًا لكتابه بفضل تعلُّم الحديث، وفضل أهله، ثم تناول نشأة مصطلح علم الحديث، والأطوار التي مرَّ بها، وأهم المصنَّفات التي أُلِّفت فيه، مفصِّلًا في أنواع الخبر باعتبار طرقه، وباعتبار وصوله متواترًا وآحادًا، وأنواعه من حيث القبول والرَّد والمشترك بينهما، معرِّجًا على صفة الراوي وشروط قبوله، وفكرة عامة عن كتب الجرح والتعديل ومراتبه، لينتقل بعدها إلى آداب الرواية بين المحدِّث وطالب الحديث، وكيفية ضبطها وطرق تحمُّلها، ثم الإسناد ولطائفه وأنواعه التي تتوزَّع بين العالي والنازل والمسلسل، ورواية الأكابر عن الأصاغر، والآباء عن الأبناء والعكس، ورواية الأقران، والسابق واللاحق، خاتمًا مادة الكتاب بفصل تكوَّن من واحد وعشرين مبحثًا، عن أنواع المرويّ، ومعرفة الرواة ودرجاتهم، والمذكورين بأسمائهم أو صفاتهم أو ألقابهم أو كُناهم، والمنسوبين إلى غير آبائهم، وتواريخهم وطبقاتهم وأوطانهم.This book offers a simplified summary of the sciences of hadith ‘the tradition of sayings by the Prophet Mohamed, and of actions he did’, directed towards Omar al-Mukhtar University students. In it, its author sought simplicity of style and ease of expression, prefacing the book by acknowledging the virtue of learning hadith and the merit of its people. The book then goes on to cover the origins of the term ‘science of hadith’, the stages it went through, and the most important works written on it. It elaborates on the types of accounts, considering its methods, transmission classification as isolated ‘Ahad’ or consecutive ‘Mutawatir’ and its types in terms of acceptance, rejection, and the commonality between them, highlighting the narrator qualities and the conditions for their acceptance, and a general overview of the books on narrator invalidation and rectification and their levels. The book then moves on to the etiquettes of narration between the traditionist and the student of hadith, how to regulate it, and methods of bearing hadith. It then discusses the chain of narrators, its intricacies, and its types that range between the elevated, descending, and connected, and the narration of the seniors on the authority of the juniors, fathers from sons and vice versa, and the narration of peers, and precedence and succession. The book concludes with a chapter consisting of twenty-one topics covering the types of narrations, knowledge of the narrators and their ranks, those mentioned by their names, characteristics, titles, or nicknames, those attributed to other than their fathers, their history, class, and homeland
