Abstract：The effects on frozen soil general characteristics by the average positive stressσm and internal friction angle φ in complex stress state are involved in the study. The formula of creep stress ,displace-ment ,thickness of frozen soil wall with ultimate state and secondary ultimate area existing simultane-ously in infinite long frozen soil wall are obtained. The formulas are universal. The formulas of dis-placement and thickness by using linear or nonlinear elastic mechanics and elastic - plastic mechanics can be obtained ,as long as make the parameters of formulaφ = 0 ,m = 1.
