天生桥二级水电站地应力测试及分析

The Crustal Stress Test and Analysis of Tianshengqiao Secondary Hydropower Station

本文主要介绍天生桥二级水电站地应力现场测试和室内测定情况,并根据水工布置、地质构造、地应力测试的结果,将地应力场进行划分,又以引水隧洞围岩、厂房边坡等工程区的应力释放现象,简述次级应力场是个动态的,随时间自行调整的相对稳定工程地应力场。

This paper mainly introduces the spot test of crustal stress and indoor determination. According to the results of hydraulic arrangements, geological structures, crustal stress tests, the crustal stress fields can be divided. The paper briefly expounds that the secondary stress fields are in a dynamic state and they are engineering crustal stress fields which are relatively stable because of antomatic time adjustment according to the stress releasing phenomena of diversion tunnel surrounding walls and factory sides and slopes, etc.
