摘要
为验证Slide和Geo-Slope两个边坡稳定分析软件可靠性和准确性,选取论解验证、均质土坡、非均质土坡和均质土坡+水4个考题算例,通过与考题裁判解对比,证明这两款软件计算结果可靠可信。以老挝南湃水电站左坝肩边坡稳定计算分析为例,进一步证明这两款软件计算结果的可靠性。结果表明:Slide上手简单、操作简便,但是Geo-Slope功能更为强大;边坡稳定安全系数对于土体容重取饱和容重或天然容重的影响不敏感;在边坡稳定计算中,将地下水位线以下土体的有效抗剪强度参数进行人为的折减是值得商榷的。
In order to verify the reliability and accuracy of Slide and Geo-Slope two slope stability analysis software, four examples of test and verification, homogeneous soil slope, heterogeneous soil slope and homogeneous soil slope ＋ water were selected. Examination of the referee solution to prove that the two software calculations are reliable and credible. Taking the stability calculation of the left abutment slope of Laos Nanbai Hydropower Station as an example, the reliability of the two software results is further proved. The results show that Slide is simple and easy to operate, but Geo-Slope is more powerful. Slope stability safety factor is insensitive to the effect of bulk density or natural bulk density on soil bulk density. In slope stability calculation, It is debatable to make artificial reductions for the effective shear strength parameters of the following soils.
