%X The improved Gauss-Newton-Marquit method is proposed for back analysis of elastic displacement for underground tunnel. The direct solution method of partial derivative is used in stochastic finite element method to complete the back analysis. Compared to the traditional Gauss-Newton-Marquit method using difference method,the efficiency of the improved method is greatly advanced. The case study shows that the improved method is more efficient in solving the back analysis problem of elastic displacement for underground tunnel and is expected to be applied to large engineering practice.
