强透水层基坑锚索及预应力抗浮锚索应用分析及研究

Application Analysis and Research on Anchor Cables and Anti Floating Anchor Cables for Foundation Pits and Main Structures in Strong Permeable Layers

文章以商洛地区强透水层基坑锚索及基础结构预应力抗浮锚索的成功实施为背景,针对锚索实施过程中可能涉及的降水及外围沉降变形进行计算分析,采取合理布置降水井、动态调整降水方式、改进锚索成孔及注浆工艺等技术手段,建立各参建单位联动协调机制,信息化施工,确保了基坑锚索及基础结构预应力抗浮锚索的成功实施并达到设计要求,满足工程需要,为类似工程提供参考与借鉴。

This paper took the successful implementation of foundation pit anchor cables and foundation structure prestressed anti floating anchor cables in the strong permeable layer of the Shangluo area as the background.It calculated and analyzed the possibld precipitation and peripheral settlement deformation involved in the anchor cable implementation process.Technical measures such as reasonable arrangement of precipitation wells,dynamic adjustment of precipitation methods,improvement of anchor cable drilling and grouting technology were adopted,and a linkage and coordination mechanism among various participating units was established for information sharing,ensuring the successful implementation of foundation pit anchor cables and foundation structure prestressed anti floating anchor cables,meeting design requirements,meeting engineering needs,and providing guidance for similar projects.
