For there are too many intensity and deformation parameters of surrounding rock that affect the deformation of tunnel,existing back analysis researches almost concentrate on optimizing algorithm,and neglect the convenience and practicability of engineering application. Due to this situation,taking a tunnel in Nanjing as the basis,combined with numerical simulation,a method of parameter back analysis of surrounding rock based on the sensitivity of itself is obtained. Based on the engineering reality with comprehensive considering of surrounding rock and supporting structure,to divide them into three zones: initial surrounding rock zone(Z1for short),the loose circle and anchor grappling coefficient zone(Z2for short)and steel and shotcrete equivalent zone(Z3for short); By confirming the initial value of mechanical parameters,the FLAC3 Dsoftware is used to simulate and analyze the different sensitivity of every parameter to different deformations,and then the procedure of inversion is determined; On the basis of this procedure,the mechanical parameter of surrounding rock is acquired by combining it with the measured value. The results show that: the main influence factor of different deformations can be acquired by sensitivity analysis,compared with common inversion methods,inverting the main factor parameter can improve the efficiency and reliability in engineering application based on the deformation; the main influence factors on crown settlement are E1(elastic modulus of Z1)and n(the elastic modulus ratio between Z2 and Z1),μ1(Poisson's ratio of surrounding rock); the main influence factors on tunnel convergence are E1,n,μ1;the mechanical parameter value according to back analysis is as follows,E1= 362. 6 MPa、n = 0. 62、μ1= 0. 30;this method is effective and rational verified by field applications.
