摘要
土石坝边坡稳定分析的常用方法是圆弧法,该种方法的原理简单,公式简洁。但需根据多次试算确定安全系数。在搜索最危险滑动面时,每给定一个滑动面,都要重新确定分条的边界、高度、宽度和分条数目等参数,计算工作量较大并且存在着不确定性,将传统圆弧法进行改进,编制程序,自动搜索最危险滑动面并确定其安全系数,简便了计算过程,并通过工程实例验证了其可靠性。
Circle method,with a simple principle and brief formula,is an essential method to analyse slope stability of earth-rock dam,but it usually need calculation of many times in order to get the safety factor.The searching of the potential slip surface,when given an new slip surface,some parameters such as slice′s boundary,height,width,number and so on must be reconfirmed,which needs a larger amout of calculation and also has uncertainty.In this paper,the authors improved the traditionary circle method,make the program,and through it the most possible slip surface can be searched and the safety factor obtained automatically,in this way,the calculation process is simplified.Using example the program’s feasible is examined.
