| 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。

| Abstract: | In order to get the targets of both the effective utilization of funds and the disaster prevention and reduction， a series 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 disaster 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. |
