摘要
以刚体极限平衡理论为基础，首次建立了拱坝坝肩整体稳定可靠度分析数学模型，导出了全概率方法分析其可靠度的计算公式，编写了相应的计算程序，并结合某拱坝实例对两岸坝肩岩体作了较详细的可靠度计算与分析，得到一些有实际意义的成果，实际计算表明，本文提出的计算方法合理，计算结果可靠，是对拱坝坝肩整体稳定可靠度分析的较好方法．
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.
