Abstract: Based on the Harbin Metro project, the mechanical properties of the silty clay and the selection of the advanced support method were studied with different water content. Through the laboratory tests, including water content test and triaxial test, the type of soil samples from Harbin Metro tunnel was identified as the silty clay and the mechanical properties of soil samples with different water content were determined, and the silty clay of Harbin Metro tunnel was sub-classified according to liquid index. Field monitoring was performed to calibrate the water content-dependent deformation and strength parameters used in the numerical simulations, and the correctness of numerical simulation was confirmed. Numerical simulation was performed with different soil parameters and different support method, and the selections of the tunnel advanced support method with different parameters were obtained by comparing the displacement, stress, stress path and the area of the plastic zone under different conditions. The obtained results could give some help for the selection of the advanced support method of Harbin metro tunnel.

Key words: stress path, stability, advanced support, silty clay, water content, surrounding rock sub-classification, deformation
