摘要: 由于岩土体的变异性,要准确地选取滑坡力学参数,有必要分析其敏感性。以重庆市黄溪镇原镇政府办公大 楼滑坡为例,采用参数敏感性分析,找出其中影响较大的影响因素,再综合室内外实验数据和参数反算的结果,运用 “参数综合取值法”选定了合理滑坡的力学参数。该方法具有很好的工程实用价值

关键词: 滑坡, 力学参数, 敏感性分析, 参数综合取值

Abstract: Due to the variation of rocks。it is important to choose the landslide mechanical parameters accurately and have a sensitivity analysis on mechanical parameters.A case study of the landslide around the previous government office in Huan- gxi Town in Chongqing is carried out.In the case study,the influence factors are found out according to the parameters sen- sitivity analysis;and then synthesize the indoor and outdoor experimental data as well as the results of parameters inverse calculation,the reasonable landslide mechanical parameters are selected by using“integrated method of parameters value”. The practice has proved that this method has a good practical value in engineering.

Key words: landslide, mechanical parameters, sensitivity analysis, integrated method of parameters value
