地下厂房围岩稳定和支护试验分析

Experimental Analysis on Stability and Support in Surrounding Rocks of Underground Power Houses

本文介绍水电站地下厂房洞室在开挖过程中进行喷锚支护后的围岩应力、变位和破坏形态的变化规律,同时对不同锚固方式的锚杆应力做了初步的探讨。

This paper presents the change regularities about stress, displacement and failure morphology in surrounding rocks of underground power houses in the process of excavation after waging anchorage support. In addition, the distribution law of anchorage bars stress for different anchorage ways is preliminarily studied.
