边坡稳定和滑坡实例计算对比分析

Comparison and analysis of slope stability and landslide cases

文章以文献中的大量边坡稳定和滑坡为工程实例,应用边坡稳定分析应力状态方法的解析公式,进行边坡安全系数的计算,计算结果与文献中的条分法、非线性模型、神经网络、有限元强度折减等方法的结果相比较,定性结果比较一致。由于应力状态法解析解具有完整的数学力学模型,大大简化了计算程序、应用软件的依赖过程,较真实地反映了实际土坡的稳定状态,可为边坡稳定设计提供依据与参考。

In this paper,based on lots of engineering cases of slope stability and landslide in the related literature,the analytical formula of stress state method in slope stability analysis is used to calculate the slope safety factors.The calculation results are compared with those of the slice method,the nonlinear model,the neural networks method and the finite element strength reduction,and the qualitative results agree well with those of them.With the complete mechanical and mathematical model,the analytical solution of stress state method simplifies the computational program and does not rely on the application software,and it truly reflects the stability state of the slope and can provide a reference for the stability design of the slope.
