摘要
本文在综合分析大田湾滑坡区域地质条件、基本特征以及滑坡形成机制的基础上,采用极限平衡理论的传递系数法对该不稳定斜坡的稳定性进行定量分析计算。然后用一套基准数据采用传递系数方法算出滑坡的稳定系数KS0,在此基础上变动其中的某一参量,其它参数固定不变,计算出该参量在其变化范围内变动时滑坡稳定系数随之变化的结果,再根据上面的计算结果求出敏感系数S,对滑坡稳定性影响因素进行敏感性分析,以指导滑坡的实际治理与监测,使治理设计更安全、可靠和经济。
Based on the comprehensive analysis of the regional geologic conditions,basic characteristic and the formation mechanism of the Datian Bay landslide region,this paper made a quantitative analysis of the stability of this unstable slope by using the transfer coefficient method of the Limit equilibrium theory.This paper calculated the stability coefficient of the landslide was KS0 by using a set of baseline data and the method of transfer coefficient.According to the above result,the author changed one parameter and kept the other parameters the same and then calculated the landslide stability coefficient changes when the above parameter varied in its range.After that,the author got the sensitive coefficient S from the above calculation results.At last,this paper gave a sensitivity analysis of the landslide stability factors in order to guide the actual landslide governance and survey,and make the management design more safe,reliable and economy.
