Based on the theory of bulk-solid coupling and classical soil mechanics,the simulation analysis of a glass fiber enhanced SMC valve inspection well under the working condition was conducted by use of finite element software ABAQUS.From the backfill test of valve inspection well,the glass fiber enhanced SMC valve well's stress distribution and deformation were obtained.The comparison of test results and the FEM results verified the correctness of the finite element analysis.It can provide the basis for the s...
