滑坡稳定分析传递系数法的讨论

Discussion on Method of Force Transfer for Stability Analysis of Slope

本文介绍了滑坡稳定分析传递系数法的由来、基本原理和工程应用,分析了条块间力的传递及公式推导中虚拟假定和现场实际之间的差别,认为传递系数法是一种工程实用的计算方法,其隐式解如用得适当,可以达到与"严格解"相近的效果。并指出,简易方法逐步被更先进而实用的方法取代是必然趋势。计算者应注意公式的适用条件、现实和假定的差异及影响计算成果可靠性的因素,避免盲目性。

The origin, the basic principle and the application of the method of force transfer for the stability analysis of slope are reviewed. The transfer of the forces between slices is discussed, and the difference between the assumption and the field conditions is considered. Based on these analyses, the said method is considered to be a kind of practical method for the stability analysis of slope. When the method is properly used, the solution is similar to the result from the method of precision solution. It is pointed out that the advanced and practical methods will certainly replace the simplified method. Engineers should pay attention to the factors which affect on the reliability of the calculation.
