Physical and Mechanical Properties of Fully Weathered Diorite in Dangjinshan Tunnel
There are long-distance longitudinal cracks in the side wall of the lining structure at the exit of Dangjinshan tunnel.The problem is caused by the geological problems of the surrounding rock mass.Therefore,it is necessary to study the physical and mechanical properties of the surrounding rock of the tunnel.In order to further understand the physical and mechanical properties of surrounding rock in this area,the method of field sampling and laboratory test is adopted to study the physical and mechanical properties of completely weathered diorite,and the strength and rigidity characteristics of completely weathered diorite under different water content are analyzed It can provide some basis for the analysis of the causes of tunnel cracking,ensure the effectiveness of the treatment measures,and is very useful for the similar tunnel construction.
