Simulation of gravity dam foundation by using mapped infinite elements

Yan Liubin (Guangxi University)  
This paper presents a coupling model of infinite and finite elements to simulat gravity dam foundation; Analysis of a 3-D half space problem and the stress and displacement analysis of a gravity dam show that the model effectively reduces the time in preparation of date and CPU time in comparison with the ordinary finite element simulation. It also improves the computational accuracy and saves time and money.
