| 摘 要： | 根据当前基坑支护形式,将桩锚支护体系中的锚索用自旋锚管取代,设计合理的桩与自旋锚管的支护体系,并对该支护体系进行稳定性验算;此外,还利用有限差分法对该支护体系进行仿真模拟。在京石客运专线明挖段施工中采用这种支护形式,并在现场对桩顶沉降和锚杆锚固力的变化情况进行了监测,发现自旋锚管在安装一段时间之后其锚固力还会继续上升,桩体位移的最大值只有3.3mm。由此得出这种支护形式完全能够满足支护要求。

| Abstract: | Based on current supporting forms of foundation pit,cables are replaced by self-screwed tube bolting in the anchor pile system,and a reasonable anchor pile supporting system is designed,then,the stability of the supporting system is checked.In addition,the supporting system is analyzed by using finite difference method.The supporting system was used in constructions of the open cut section of Jingshi Passenger Dedicated Lines,and changes of pile top settlement and bolt anchoring force were monitored on site... |
