摘要
本文研究了实验室内测定岩体地应力的两种新方法——声发射法和应力应变曲线特征点分析法。用这两种方法对天生桥二级(坝索)水电站的岩样进行了测试,并与现场测量结果进行了比较。
In this paper, two new methods of determining in-situ stresses of rock masses in laboratory, acoustic emission method and analysis of typical points of stress-strain curves are investigated. The rock samples obtained from the second Tian Shen Qiao (Ba Suo site) Hydroelectric Station are measured by the methods. Their results are compared with the data obtained by field measurements.
