| 摘 要： | 鉴于膨胀岩物理力学特性及其工程特性的研究，结合深基坑支护工程使用时间短的自身特点，寻找膨胀岩抗剪强度衰变期与基坑支护工程使用安全期之间的关系，提出如何利用这种时差效应，为工程带来更多经济效益的设计取值方法。以南宁市昌泰东盟园深基坑支护工程为例，通过不同时期的勘察取样以及采取的不同试验方法分析，进一步佐证膨胀岩时效性在深基坑支护工程设计施工中的应用价值。

| Abstract: | Research of the projecting feature depending on swelling rock physical and mechanical characteristics and the engineering characteristics. The characteristics bracing engineering of deep foundation pit combined with substructure. Look for relations of decay period and safe period, the timeliness effect was put forward by their relational, For this to made economic effect design methodology. A Case Study of Nanning, which was testified further by the timeliness effect of bracing engineering of deep foundation pit on swelling rock. |
