摘　　要：由于黄土的结构性和湿陷性,黄土基坑具有与其它基坑不同的特点。为了研究黄土基坑复合土钉支护的施工方法,对黄土基坑的特点进行了深入分析,研究了黄土结构性和湿陷性对基坑施工的影响,结合西安市区某工程实例,提出了黄土基坑复合土钉支护的施工技术措施。The loess excavations have its different characteristics compared with the others due to its structural property and collapsibility. In order to research the construction methods of composite soil - nailing in loess excavations, some characteristics of loess excavations are analyzed thoroughly. The influences of structural property and collapsibility on construction method are studied, and the proper construction technical measures are introduced with an actual project in Xi＇an.
