摘要
Abstract
Soft and hard interbedded rock mass is a geological environment often encountered in the construction of hydraulic tunnel,and the study of its influence on the safety and stability of surrounding rock has important theoretical significance and engineering value.Based on the concrete project,the significant influence of the layer thickness ratio and rock layer thickness on the stress,displacement and plastic zone characteristics of the surrounding rock is discussed by numerical simulation,and the corresponding variation rules are obtained,which can provide necessary support and reference for theoretical research and engineering construction design.The maximum compressive stress and plastic zone of the surrounding rock appear at the waist of the arch,so it is suggested to strengthen the stress and deformation monitoring in this part during construction.关键词
