The Effect of Cut-off Wall on Seepage and Uplift Pressure under Earth Dam (Case Study: Shamil Dam in Iran)
Design of earth dams and their problems are important during construction and after it,because of their potential hazards and failure for downstream population. The dam foundation seepage control the the importance from the perspective of a major engineering project and explain the economic performance of each project is allocated. among activities that can be used to prevent piping phenomena a...
متن کاملnumerical stady of pore pressure development and dissipation in core of masjed-soleyman rockfill dam
the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...
متن کاملNon-linear Analysis of Stress and Strain of Concrete-faced Rockfill Dam for Sequential Impoundment Process
The rockfill is modeled as nonlinear elastic material, whose stress-dependent tangent modulus is related to the confining pressure. The parameters of constitutive relationship of stress and strain are determined by tri-dimensional compression test in laboratory. The model applied in this study adopts the technique of element birth and death to simulate the sequential impoundment process of conc...
متن کاملRemote Sensing of Deformation of a High Concrete-Faced Rockfill Dam Using InSAR: A Study of the Shuibuya Dam, China
Settlement is one of the most important deformation characteristics of high concrete faced rockfill dams (CFRDs, >100 m). High CFRDs safety would pose a great threat to the security of people’s lives and property downstream if this kind of deformation were not to be measured correctly, as traditional monitoring approaches have limitations in terms of durability, coverage, and efficiency. It has...
متن کاملWall stress and deformation analysis in a numerical model of pulse wave propagation.
To simulate pulse wave propagation, we set up a wave propagation model using blood-wall interaction in previous work. In this paper, our purpose is to investigate wall stress and deformation of the wave propagation model. The finite element method is employed for solving the governing equations of blood and wall. Our results suggest that there are two peaks in the circumferential stress and str...
