摘要
以四川省芦山县黄水河岩质边坡为例分析,采用赤平投影法进行了初步的判断,根据赤平投影平面图进行简单的定性的地质分析。针对边坡的稳定性,采用部分强度折减法,定量计算出边坡的整体稳定性系数。结果表明:以赤平投影法分析的黄水河岩质边坡处于基本稳定状态,仅能确定边坡局部变形情况,以此来界定整体的稳定性情况;采用部分强度折减法,可以更好地描述出黄水河岩质边坡渐进破坏过程,并根据临界点的不同位置,得到不同情况下的稳定性系数。
In this paper,the rock slope of Huangshui River in Lushan County,Sichuan Province was taken as an example.First,the stereographic projection method was used to make a preliminary judgment,and a simple qualitative geological analysis was carried out according to the projection plane map of Akabira.Secondly,according to the stability of the slope,the overall stability coefficient of the slope was calculated quantitatively by using the partial strength reduction method.The results show that the rock slope of Huangshui River analyzed by Akabira projection method is in the basic stable state,and only the local deformation of the slope can be determined to define the overall stability;The progressive failure process of Huangshui rock slope can be better described by using the method of partial strength reduction,and the stability coefficients under different conditions can be obtained according to different critical points.
