| 摘 要： | 山地城镇在工程建设中面临着许多边坡问题。目前确定岩质边坡破裂角的方法有两种：即《建筑边坡支护技术规范》规定的方法和《工程地质手册》规定的方法,但这两种方法确定的岩质边坡破裂角存在较大差异,本文对这两种方法的理论公式进行推导和做出比较,在FLAC程序数值模拟软岩边坡变形破坏并找出其破裂角的基础上,得出采用《工程地质手册》规定的方法确定岩质边坡破裂角更加合理、安全的结论。

| Abstract: | Many mountainous cities are facing slope problems during project construction. At present, there are two methods to determine cracking angle for rock slope, namely, the method from "Technical Specification for Retaining Structure in Excavation" and the method from "Handbook of Engineering Geology". However, there is obvious difference between cracking angles of rock slope by these two methods. In this paper, the theoretical formulas of these two methods are derived and compared. Based on analyzing the results of FLAC numerical simulation for soft rock slope, it is concluded that the cracking angles of rock slope determined by the "Handbook of Engineering Geology" are more reasonable and safe. |
