摘要
为了更好地了解土钉支护基坑的内力和变形性状,利用商业软件FLAC3D对某一工程实例进行了三维数值模拟,详细分析了其应力特征及变形特征,还计算了土钉倾角和土钉间距的改变对基坑变形的影响.计算结果与实测结果基本吻合,表明用FLAC3D模拟土钉支护是可行的.计算结果同时也表明,基坑变形有明显的空间效应,应选用较小的土钉倾角和合理的土钉间距.
In order to know well the internal force and the deformation of foundation pit of soil nailing, the three -dimensional numerical simulation studies are carried out for a practical engineering. Stress and deformation properties are analyzed in detail and the change of the inclination of soil nail, the spacing of soil nail to the influence of the deformation of foundation pit are calculated by FLAC^3D in this paper. The agreement between the computed and the measured results is good, which proves that soil nailing is simulated by FLAC^3D is feasible. At the same time, the calculated results are shown that the deformation of foundation pit has strong three - dimensional effect, and less inclination of soil nailing, reasonable spacing of soil nailing should be chosen.
