摘　　要：本文在深基坑土钉 (喷锚网 )支护现场试验的基础上 ,运用 FL AC程序对该试验深基坑进行了施工过程中土钉应力分布规律 ,以及基坑边壁土体的变形大小和规律的分析 ;并对比现场实测结果 ,得到了几点关于土钉工作性能和基坑变形的结论。Based on the in-situ tests of soil nailing support of deep foundation, an analysis with FLAC program was carried out on the distribution of stress for soil nailing during construction, size and development of deformation for soil in side-wall of foundation pit. Some conclusions have been drawn on performance of soil nail and deformation of foundation pit. [
