摘要
结合唐山市第三空间综合体深基坑工程,基于FLAC3D软件的弹塑性有限差分分析,对基坑坡顶水平位移实测数据与数值模拟结果进行了对比分析。研究表明:土钉和预应力锚索相结合的复合土钉支护方法,能够较好地控制基坑变形的发展。该工程的成功实施,对今后类似工程具有较大的借鉴价值。
Through an elastic-plastic analysis of FLAC3D program based on the explicit difference method,and from the case of urban complex of the third space deep excavation project in Tangshan on composite soil nailing combined with general soil nail and prestressed anchor.Numerical simulation is carried out and the horizontal displacement on the top of pit foundation,with measured date is discussed.The analysis shows that the composite soil nailing can largely restrain the pit foundation deformation.The successful application provides useful reference to similar projects in future.
