摘要
以武汉城市花园基坑支护项目为依托,建立基坑支护模型,分析双排桩桩长、锚索长度及预应力对支护结构变形、内力的影响,其模拟结果与监测资料相吻合,两者对比得出:桩长、锚索长度达到一定值后,再增加其长度,对双排桩锚支护结构变形和内力影响不明显,但适当增加锚索预应力,能够有效限制基坑的变形。
This study,based on Hankou City Garden foundation pit supporting project in Wuhan,set up the foundation pit supporting model,analyzed the impact of the length of double-row pile,the length of cable and prestress on the deformation and the internal force of supporting structure.The simulation result is consistent with the monitoring data.Comparison between the two methods proves that,after reaching a certain value of the length of the pile and the length of the cable,the increase of its length exerts no effect on the deformation of supporting structure and internal force of double-row pile anchors.But an appropriate increase of the prestress of anchor cables will effectively limit the deformation of foundation pit.
