Deformation Mechanism of Hard Cataclastic Rock Tunnel under High Geostress
摘要
Abstract
The hard rock tunnel with high geostress may encounter rockburst and the soft rock tunnel with high geostress may suffer large deformation,which happen frequently in mountain tunnel construction.Many researches have been conducted and the large hard flash rock deformation in Guanshan tunnel construction is exceptionally a rare case.This paper intuitively expounds the features and mechanism of deformation and failure of the hard cataclastic surrounding rock mass based on the study of the geological environmental background,rock composition,rock mass structure and characteristics,in-situ stress in the tunnel area and on the theoretical analysis,which provides a basis for taking economic and reasonable support measures to control tunnel deformation.关键词
