摘　　要：介绍了国内外边坡稳定中的滑裂面形式,并分析了各种滑裂面形式的优缺点,在此基础上提出了一种新的滑裂面形式———对数螺旋滑裂面,对此种形式从几何构造到受力分析进行了探讨,说明了这种滑裂面形式优于其他滑裂面形式的特点。This article carries on the brief introduction to in the domestic and foreign stabilities of slope slip crack surface form, and has analyzed each kind of slip crack surface form good and bad points, introduced one kind of new slip crack surface form logarithmic spiral slippery fracture in this foundation. This article plants the form to carry on the brief introduction regarding this from the geometry structure to the stress analysis, explained this kind of slip crack surface form surpasses other slip crack surface forms the characteristic.
