摘要
Through cyclic triaxial tests for the reinforced soft clay around the tunnel of Baoshan-Hailun station of Shanghai No.4 subway line, the analysis of pore water pressure was made on the reinforced soft clay under subway train loads. The result shows the influence rate of pore water pressure on vibration frequency, amplitude of dynamic stress, consolidation ratio and over consolidation ratio is 0.722, 15.821, 0.944 and 6.628 respectively. Main factors which affect the change of pore water pressure are amplitude of dynamic stress and over consolidation ratio.
