摘　　要：本文基于GDS应力路劲三轴仪及常规固结、三轴仪测试基床系数,并进行修正,同时采用了基于静止土压力系数及压缩模量的公式计算基床系数,将试验值、计算值与地铁规范经验值和现场标贯换算值进行了对比分析。The coefficient of subgrade reaction was obtained and corrected through GDS stress path triaxial test,the conventional consolidation test and triaxial compression test.Meanwhile,the coefficient of subgrade reaction was calculated by using an equation based on the coefficient of static earth pressure and compression modulus.The comparative analysis was made among the testing value,calculation value,the empirical value stipulated in metro code and the field SPT value.The coefficients of subgrade reaction based on static earth pressure and compression modulus is very consistent with the empirical value and SPT value.
