Numerical Simulation Research on Uplift Performance of Rock Embedded Foundation for Hard Rock Geological Transmission Lines Based on FLAC3D
In order to solve the problems of high cost and limited test site in analyzing the bearing performance of rock embedded foundations using true type tests,the finite difference program FLAC3D is used to determine the rock mechanics parameters of hard rock through numerical simulation and inverse analysis.The bearing performance of the jar-type rock embedded foundation and the excavated rock embedded foundation is numerically simulated under hard rock conditions,and the uplift load-displacement curves,failure modes,and bearing performance of rock embedded foundations with different buried depths are obtained.The results show that the excavated rock embedded foundation has better bearing performance under the condition of hard rock.
