门字形锚桩围护结构参数对深基坑工程水平位移的影响

大量工程实践证明门字形锚桩支护结构可以有效地限制深基坑的水平位移,本文结合工程实际情况,用flac软件对门字形锚桩结构进行了数值模拟计算,通过对不同锚桩长度、桩锚倾角变化、锚桩的间距改变对深基坑水平位移的影响的计算分析,并与实测结果进行对比,得到了锚桩的临界长度等,这些结果对深基坑支护结构设计具有一定的参考价值。

large numbers of practice of project have proved that the timbering structure with the shape of ＂door＂can restrict availably horizontal displace of the pit. Combined with the projects examples, horizontal displace of the pile is influenced by the change of pile length, the angle of the anchored pile,space of the pile.deduces some conclusion that has certain practical meaning to research of the design of structure.gain critical length of the pile which have definite reference manual to the design of pit.
