摘要
本文通过对新滩斜坡实际位移资料的分析和滑坡模型的力学计算,给出了松散堆积层斜坡剪出口形成区的地质位移特征及力学判据。并用以对新滩滑坡某些代表部位进行了反演分析和计算,结果与滑坡实际剪出口部位相吻合。这说明了可以运用地质位移和力学判据对堆积层斜坡剪出口的形成部位和条件进行综合分析和计算。
Through the analysis to the practical displacements of Xintan slope and mechanical calculation to the landslide modes, this paper has given out some characteristics of geology - displacement and mechanical criterions for the shear - outlets of the talus deposit slopes. Meanwhile, some opposite analysis and computation have been carried out to some representive points of the Xintan slope by means of the criterions of geology-displacement and mechanics, and the analysis results coincide with the practical position of the shear -outlets of the Xintan Landslide. So it shows that the criterions of geology-displacement and mechanics can be applied to make a comprehesive analysis and calculation is determining the shear-outlets positions of the talus deposit landslides.
