摘要: 冻结壁稳定性是由其所承担的外荷载大小和变形量决定的,在考虑冻结壁的卸载 过程及其与周围土体共同作用的同时,还考虑了冻结壁的蠕变变形,得出了与周围土体共同 作用的冻结壁的黏弹塑性计算模型,并推导出冻结壁黏弹塑性区的应力、变形及其外荷载的 解析式;并通过计算,得出的冻结壁位移与实测位移基本一致.

Abstract: The stability of frozen soil wall is determined by its applied load and deformation. The unloading process of the frozen soil is taken into account, together with the interaction between the frozen soil wall and the surrounding earth mass. At the same time, the creep displacement is also taken into account in the stability analysis of frozen soil wall. The expressions of the stresses and displacement of frozen soil wall are obtained based on the viscous-elastic-plastic theory. The calculated displacement of the frozen soil wall is well consistent with those measured in-situ.

Key words: frozen soil wall, viscous-elastic-plasticity,
