摘要
以西安市某一深基坑工程为例,采用极限平衡计算方法对土层性质、土钉长度布置、土钉倾角变化等参数对深基坑土钉支护结构稳定安全系数的影响进行分析研究,为黄土地区深基坑土钉支护结构的优化设计提供重要的参考依据。
Combined with an example of a deep excavation in Xi＇an region, the studies of the parameters influenced on the stability of the soil-nail supporting are carried out by a limit equilibrium method, including the character of soil, the disposal of nail length, and the changes of inclination of soil-nail structures. Some qualitative conclusions can provide some references for the design of supporting structures in a loess area.
