搅拌桩复合土钉支护基坑的FLAC-3D数值模拟分析
摘要:利用FLAC-3D有限差分软件建立模型,对10 m深均质土基坑进行直立开挖,采用搅拌桩复合土钉结构支护开挖坡体,对坑壁的水平位移、墙后地表沉降位移、坑底回弹位移、土钉轴向内力和搅拌桩对控制水平位移的作用等方面分别进行了详细分析,总结出一些搅拌桩复合土钉支护均质土基坑的规律性结论,对工程实践提供参考。
Abstract:In this paper,one homogeneous soil pit of 10m deep is modeled by the software of FLAC 3D,the slope,which is supported by soil-cement mixied pile and composite soil nailing supporting structure is analyzed in detail by the ways of the horizontal displacement on the pit wall.Vertical displacement on the ground and on the bottom of the pit and the axial internal force of the soil nail.Finally,the regularity conclusion about the homogeneous soil pit which is supported by soil-cement mixed pile and composite soil nailing supporting structure is summarized,which provided references to the application of Pit supporting Engineering practice.
