摘　　要：为了达到有效利用资金和防灾减灾的目的,本文提出了一系列地震工况下岩体坡角开挖的优化设计方案,并通过类比分析提出了一种简单的安全预测方法。该法可以初步判断边坡强度弱化到一定程度后的抗灾能力,对危岩的情况及时采取加固措施,对防灾减灾具有重大意义。In order to get the targets of both the effective utilization of funds and the disaster prevention and reduction, a se- ries of optimized design schemes for the excavating angle of rock slope under seismic conditions are put forward herein, and then a simple safety prediction method is presented through the relevant analogy analysis as well. With this method, the dis- aster-resistant capacity of a rock slope can be preliminarily estimated, when it is weakened to a certain extent. Therefore, the method has an important significance of disaster prevention and reduction for taking strengthening measures on dangerous rock mass in time.
