摘　　要：复合土钉支护结构以其施工便捷、经济和支护效果好等诸多优点,在当前的基坑工程中得到越来越广泛的应用。本文在深基坑复合土钉支护现场试验的基础上,运用FLAC程序对该工程的基坑开挖过程进行模拟,主要计算了基坑周边土体的水平位移和沉降,并对比现场实测结果。得出结论,采用FLAC程序的计算与实测结果是吻合的。With such advantages as easy to construct, economical effect and nice purpose of shoring, the compound soil nailing support has been widely used in the shoring of foundation pit. Based on the site tests of the compound soil nailing support of deep foundation, an analysis with FLAC program was carried out on the process of construction with the emphasis on the level displacements and settlements of soil around the foundation pit. Some conclusions have been drawn on deformations of soil around foundation pit.
