Remote 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 کاملDynamics Behavior investigation of Concrete Gravity Dams by Deep Underwater Explosion Method
In this research, a deep explosion in the reservoir of a concrete gravity dam has simulated by the coupled Euler –Lagrange finite element method. The validity of explosion hydrodynamics pressure has compared with Taylor empirical formula. The surface sloshing not considered due to deep explosion. The dam and its retained water excited by detonating large explosive charges in deep water upstrea...
متن کاملsph simulation of waves associated with underwater explosion
the current manuscript presents the validation of smoothed particle hydrodynamics (sph) techniques for wave generation by underwater explosion, utilizing the so-called dualsphysics numerical model. this numerical method is used to analyze generated waves which are initiated by man-made or natural explosions below free surface level of sea. in spite of the modeling limitations (e.g. absence of o...
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...

A procedure is presented for simulating the sequential impoundment process of concrete-faced rockfill dam using nonlinear finite element method. 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 pr...
