Research on the joint bearing mechanism and sensitivity of surrounding rock sharing rate of buried water conveyance tunnels
Xiaoshuang Qiu
In view of the structural bearing performance issues of buried water diversion tunnels, the paper conducted a series of numerical simulation study on the joint bearing mechanism of steel lining-concrete lining-surrounding rock. Based on the actual background of a power station project in the western area of China, macroscopic and mesoscopic finite element models were established by using ABAQUS software. The influence laws of multiple parameters such as rock mass category, steel lining thickness
