本文提出一个按圆柱形滑动面的假定来确定土坡稳定性的图解法,供研究参考。这个方法是参考H.Raedschelder Ghent(Belgium)土坡稳定分析的图解法及苏联B.B.阿利司朶斯基教授的土坡稳定计算法而推导出来的。在理论上,它比目前国内工程设计中仍在采用的条分法合理,而在运用上,它又比条分法以及上述的H.Raedschelder Ghent和B.B.阿利司朶斯基教授的方法简便,如果把这个作图法用之于地基稳定分析。它还能代替格立兴教授的地基稳定分析法,其方法较简易,而精确度并不差。
This paper presents a graphical method for determining the stability of soil slope based on the assumption of a cylindrical sliding surface for reference. This method is derived from the graphical method of the H.Raedschelder Ghent (Belgium) soil slope stability analysis and the soil slope stability calculation method of Professor B.B. Aliesdusky of the Soviet Union. In theory, it is more reasonable than the sliver method still used in current domestic engineering design. However, in application, it is more convenient than the method of segmentation and the methods of Professor H.Raedschelder Ghent and BB Alysdowski described above. If this mapping method is used for foundation stability analysis. It can also replace Prof. Grising’s foundation stability analysis method. The method is simpler and the accuracy is not bad.
