Because of the current situation where stability research filled-slope reinforced by a frame with prestressed anchor-plates lags behind actual engineering application, based on ultimate balance theory, calculation formulas factor under four arc slip surface filled-slopes are derived using improved Bishop method; corresponding search method most dangerous is given and pullout force improved. Bas...
سابقه و هدف: در سدهای خاکی، با توجه به ویژگیهای متفاوت مصالح هسته و پوسته، نشستهای ناهمگن بین بخشهای مختلف سد رخ میدهد. این عمل منجر به پدیده قوسزدگی میشود که سـبب ایجـاد برخـی ترکهای عرضی در بخش نفوذناپذیر سد به ویژه در نزدیکی اتصال سد به دیوارهای جانبی شده که این ترکها در اولین دوره آبگیری و با اعمال ناگهانی فشار آب مخزن به هسته، میتوانند گسترش یافته و در نهایت و در حالات بحرانیتر م...

به طورکلی ایمنی سد تنها به طراحی و ساخت آن مربوط نمیشود، بلکه به رفتارنگاری کاملی از عملکرد آن در اولین دوره آبگیری و بهرهبرداری و همچنین سرویسدهی منظم در طول عمر سد وابسته است. در این پژوهش جابجاییهای قائم و افقی سد ایوشان با استفاده از نتایج ابزاردقیق در یک دوره زمانی هشت ساله در سه دوره ساخت، اولین آبگیری و بهرهبرداری تحلیل شده است. مدل عددی بزرگترین مقطع سد توسط نرمافزارهایGeostudio و...
A future development site of a housing estate, an abandoned-brick yard with clayey slopes was studied in details to assess slope stability and to calculate the factor of safety. The Oligocene clay, the former raw material, is divided into two different geotechnical units in the clay pit. The lower one consists of grey impermeable clays while the upper unit is characterised by yellowish weathere...
Three case studies involving the use of numerical models are presented in this paper. First, a comparison of FE modelling of a deep excavation is made using 2-D finite element software, SAGE-CRISP and PLAXIS. In the second study, benchmarking is made between results obtained from 2-D FE modelling using PLAXIS and well-established 3-D centrifuge studies for the case of an existing single pile an...
Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid cyclic loading. Liquefaction and related phenomena have been responsible for huge amounts of damage in historical earthquakes around the world. Modeling of soil behavior is the main step in soil liquefaction prediction process. Nowadays, several constitutive models for sand...
Increasing the pore water pressure in the body of dams will reduce the effective stress and thus reduce the shear strength of the body materials of the dam, which can lead to dangerous results and cause instability of earth dams. According to nonlinear behavior of earth dam, behavioral models of Mohr–Coulomb and hardening soil model are used to model the dam and body materials. In this study, u...
The field performance of a geotechnical structures including its failure mechanism should be evaluated in detail before construction in order to minimize the possibility of potential failure. In this paper, the application of soil nailing system is documented in a detailed based on case study in the north of Tehran, Iran. The total excavation depth for a 15 storey residual building wall brought...
Introduction the expansive soil shows obvious volumetric changes under changing moisture conditions. these volumetric deformations usually result in differential movements of shallow foundations resting on it. consequently, structural damages could happen if no special measures would have been taken during the design process. this article illustrates the possibility to predict such movements us...
