| 摘 要： | 针对基坑工程领域土拱理论，分析了几个值得探讨的问题。土拱的存在形式是三维的，根据不同位置将土拱分为3类：桩间拱、桩后侧向拱和垂向拱。针对地下水对拱的破坏效应，提出了微结构失稳突变模型。对土拱的分析探讨期待对土拱理论的发展和完善起到积极作用。

| Abstract: | Soil arches effect is a hot topic in foundation project. In this paper, we analyzed several the questions which are worth discussed, for example the existence of soil arches and the groundwater to the destruction effect of arches. We proposed the constructive opinion, and anticipated to take a positive role in the development of soil arches theory. |
