| Abstract: | ased on the limiting equilibrium theory of the rigid body,a mathematical model for reliability analysis of abutment stability against sliding is developed in this paper.According to the model, calculating formulas are given in total probability. Furthermore,a practical program is made and used in an example of an arch dam. For the abutments of both sides, reliability analysis is discussed in detail and some useful results are obtained.The example shows that the calculating method presented in the paper is reasonable and the program can be widely used in reliability analysis of abutment stability against sliding. |
