| 摘 要： | 滑面指标反算的算法很多,其中基于传递系数法的有代表性的算法就多达四种,这四种算法虽然都以传递系数法为基础,但其计算结果多数情况下却不一致,甚至相差较大。为了弄清计算结果出现差异的原因及四种算法的优劣,本文对这四种算法进行了大量的理论分析和工程试算比较,结果表明,在各滑段均无负值下滑力及极限平衡状态(稳定性系数为1.0)下,这些算法的结果是一致的。在其它情况下,末段法过于强调末滑段的作用,容易出现不合理的计算结果;显式法不能合理地考虑有负值下滑力的滑段;因此推力法或隐式法是较好的滑面指标反算算法。

| Abstract: | There are a lot of algorithms to back calculate the slide face parameter,and four of them are representative algorithms that depend on the Transmitting Coefficient Method(TCM).Although the four algorithms all depend on the TCM,but the analysis results of them usually are not equal,sometimes their results are in wide difference.This paper did a lot of comparative work of theory analysis and trial calculation to find out the reason that caused the difference,and to find out which algorithm is the best.This re... |
