软土区桩—土—锚组合深基坑支护数值试验研究

Numerical test on piles-soil-anchors combined deep excavation support in soft clay

采用PLAXIS数值计算分析方法,对软土区深基坑桩—土—锚组合支护进行分析,提出了基坑开挖过程不同深度条件下双排桩、加固土墙和锚杆三者所起的作用及其作用比例,计算表明地下2层的深基坑组合支护体系中双排桩与加固土墙两者起主要作用,而对于锚杆根据实际工程可进行优化。

The PLAXIS numerical analysis method is used to analyze the piles-soil-anchors combined deep excavation support.Study on the role of the three structions for two-row-pileswall,reinforcement soil wall and anchors under different excavation depths.The calculation shows that two-row-pileswall and the reinforcement soil wall play major role in the excavation support structure,and the anchors can be properly optimized according to the actual excavation engineering.
