不同稳定性计算方法在滑坡中的应用研究

Application Research of Different Stability Calculation Methods in Landslide

对Geo-Studio软件进行介绍,并对不同滑坡稳定性计算方法进行说明。介绍保山市某项目滑坡的发育规模、边界条件及岩性特征,最后选取该滑坡的典型剖面建立计算模型,综合试验法、反算法及工程经验法进行合理的岩土力学参数取值,最后通过稳定性计算,对结果进行分析。研究结果表明:该滑坡的安全储备略有不足,M-P法的计算结果与实际情况最为接近。

The Geo-Studio software is introduced and different stability calculation methods are explained.The development scale,boundary conditions and lithology characteristics of Baoshan introduced.Finally,the typical section of the landslide is selected to establish the calculation model.The comprehensive experimental method,inverse algorithm and engineering experience method are used to calculate the reasonable geotechnical parameters.Finally,the stability is adopted.The calculation and analysis of the results show that the safety reserve of the landslide is slightly insufficient,and the calculation result of the MP method is the closest to the actual situation.
