| 摘 要： | 人工冻结法是利用冻土强度远大于融土这一特性，进行地下工程施工场地维护的一种方法.将这一方法用于深基础坑壁支护具有广阔的应用前景.文中类比地下连续墙和钢板桩模型，提出了采用等值梁法、悬臂梁法和薄板理论计算模式来计算人工冻结挡土墙厚度的设计原则，为今后更好地推广应用人工冻结技术找到了理论依据，也为地下工程施工开辟了思路．

| Abstract: | Artificial ground freezing is used to constructe site supporting of underground engineering according to the fact that the strength of frozen soil is much larger than that of frozen soil.This method will have broad prospect in deep base pit of underground engineering.By comparing the design models of continuous underground wall and steel pile wall,and calculating method of the some designing principles of equivalent beam pattern,cantilever beam pattern and thin-slab theory pattern,were suggcstcd in this thesis. |
