Abstract Stochastic calculations，by combining the random field theory and the finite difference analysis together with Monte Carlo simulation，are used to carry out the sensitivity analysis of spatial variability of soil parameters to surrounding-soil response induced by tunneling. The effects of coefficients of variation(COV) of Young?s modulus(E)，Poisson?s ratio( )，cohesion(c) and friction angle( ) on the surrounding-soil response were investigated and discussed in detail. Results show that the main influence factors on surrounding-soil response are arranged in the order of spatial variability of internal friction angle，Young?s modulus，cohesion and Poisson?s ratio. The higher the variation level of the parameters，the greater the sensitivity of the parameters. Additionally，the influence of spatial variability of Poisson?s ratio on surrounding-soil response can be neglected in stochastic analysis. The influence of cohesion can be considered comprehensively according to the variation level.

Key words： tunnelling engineering shield tunneling spatial variability sensitivity analysis surrounding-soil response variation level
