| 摘 要： | 在深基坑土钉支护设计中，目前存在着混乱的现象，如何既经济又安全可靠地设计土钉支护方案成为岩土工程界一个关键而又迫切的问题。本文从土钉受力及基坑变形控制等方面出发，对土钉支护中几个关键性问题进行了较为详细的分析，提出了土钉支护设计中土钉长度、间距的确定思想，并对其他一些问题做了较为详细的分析与探讨。

| Abstract: | There exists a chaotic phenomenon in deep foundation pit bracing by soil nailing at present.How to design a soil nailing bracing becomes a key and urgent problem in geotechnical circle.Based on the forces acting on the soil nails and the slope deformation control,this paper discusses serveral key problems associated with soil nailing in multiple respects, puts forward a thought to determine the soil nail's space, the lenth and driving angle for desigh,and some other key problems are also discussed. |
