摘要：
In this paper, the theologic behavior of soft rock tunnel is analyzed by a three-dimensional visco-elastoplastic mechanical model. The paper presents an iterative method of variable visco-plastic stiffness and gives an accelerating iterative formula. The method both has faster computation rate and can keep convergence stability. The analysis results of an engineering show that the computation method can fully describe the theologic behavior of soft rock tunnel.
