Investigate probability of damage of Earth dam under Near-field and Far –field earthquake : Case study Gotvand earth dam
The main goal of preset research is investigate the effects of vertical component of Near-Fault and Far-Field earthquake records on the probability of overtopping induced damage of earth dam due to the reduction of freeboard due to the settlement of dam crest. In this respect 12 different earthquake record are selected. Nonlinear dynamic analysis of earth dam is implemented with FLAC 3D using F...
متن کاملBreak fill-dam simulation using GeoStudio (case study: Safarood earth dam, Kerman)
One of the main reason of earth-dam breaks is inner erosion which is caused by washing fine soil particles and finally lead to seepage inside the dam. Seepage will decrease effective tension in the earth-dam's core and arching phenomena is occurred. More settlement of core than to shell is the consequence of arching and occurrence of cracking. In this paper, GeoStudio software based on finite e...
متن کاملSeepage Control in a High Concrete Face-Rock Fill Dam Based on the Node Virtual Flow Method
Abstract: The seepage control system of a high Concrete Face Rock-Fill Dam (CFRD) may have anti-seepage deficiencies during both construction and operation. In order to solve these, the three-dimensional Finite Element Method (FEM) model was built based on dam body filling, anti-seepage system, defect location and bedrock distribution. The seepage field simulation and computation were carried o...
متن کاملmultigrid method to solve free surface flows
in recent years, many different methods have been developed to simulate free surface flows coupled with moving bodies. in this paper, for simulating ship maneuver, vof method (cicsam) and also for coupling velocity field and pressure a fractional step method are used. to increase simulation accuracy, the mesh size should be significantly fine. unfortunately, fine grid causes increase in simulat...
متن کاملA penalty method and a regularization strategy to solve MPCC
The goal of this paper is to solve Mathematical Program with Complementarity Constraints (MPCC) using nonlinear programming (NLP) techniques. This work presents two algorithms based on several nonlinear techniques such as Sequential Quadratic Programming (SQP), penalty techniques and regularization schemes. A set of AMPL problems were tested and the computational experience shows that both algo...
