摘　　要：　运用FLAC程序模拟了土钉长度、倾角、布置方式以及土层强度参数的变化对基坑水平位移、土钉最大轴力的影响。模拟结果表明:为控制基坑变形,应适当增加土钉长度,但长度也不能过长;为控制基坑变形,土钉宜水平或接近水平设置。An FLAC program is carried out to simulate the change of nail's length,inclination,assign the way and soil layer parameter to the influence of the horizontal displacement of foundation pit and the greatest axel strength of soil nailing. The result of study shows: In order to control the deformation of foundation pit, we should increase soil nailing length properly, but it can not be too long either; In order to control the deformation of foundation pit, the soil nailing should be nailed to the direction of the level or close to level.
