Using the basic idea of virtual resistance method that approximate simplified method about space problem of surrounding rock and support in study of soft rock tunnel. The existing results of the displacement of shaft frozen wall measured in situ ,model tests and numerical simulation are compre‐hensively analyzed. The formulas of creep stress ,deformation and displacement of infinite long frozen wall and displacement of semi‐infinitive long frozen wall near excavation face are given.After analyzing distribution characteristic of displacement of finite excavation height frozen wall ,the formulas(11) and (15) are proposed for expressing the displacement distribution of the surface of infinite long frozen wall. The(21) and (25)formulas of thickness of finite excavation height frozen wall by strength condi‐tion and displacement condition are obtained. Finally ,the calculation method of thickness of finite ex‐cavation height frozen wall is illustrated by computing examples.
