研究涉及了冻土在复杂应力状态下平均正应力σm 和内摩擦角φ对冻土特性的影响。得到了无限长冻结壁同时存在极限和次极限状态区时的蠕变应力、位移和冻结壁厚度的计算式。其有关算式具有普适性，只要在算式中令φ＝0，m ＝1就可得到线性或非线性的按弹性力学或弹塑性力学方法得到的冻结壁厚度和位移计算式。

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.
