| 摘 要： | 在西南山区,受新构造运动影响,部分岩体中地应力较高,因此在地下洞室开挖过程中经常遇到岩爆现象。本文在双江口水电站前期勘测资料的基础上,结合筹建期开挖1#导流洞岩爆发生的规律,经过统计分析,总结了双江口水电站地应力分布特征及岩爆成因,提出了防治建议。

| Abstract: | Rock burst often occurs during tunnel construction in the mountain area,southwest China as a result of high ground stress due to strong neotectonism.This paper puts forward suggestion on the prevention and cure of rock burst for the Shuangjiangkou Hydropower Station based on field investigation data in combination with analysis of ground stress distribution and rock burst genesis as well as rock burst regularity in construction of diversion tunnel No.1. |
