摘　　要：针对金融街融景城A2项目灌注桩施工过程中遇到地下洞穴群的情况,为有效保证灌注桩施工质量,首先对地下洞穴探明前未施工的灌注桩部位的洞穴位置勘探、基桩判定、灌注桩基础穿越地下洞穴群的模板设计与安装,钢筋安装,混凝土浇筑的施工工艺进行详细阐述;最后对地下洞穴探明前已施工的灌注桩进行移位处理。通过采用穿越地下洞穴灌注桩施工技术,不但确保了工程质量、施工工期,而且起到了对地下环境资源的保护作用。In view of the Financial Street the group encountered underground cave into King City A2 project pile construction process, to ensure the quality of the pile, the pile location of underground cave proved before the construction of the underground cave exploration through underground caves, position determination, pile foundation pile through underground caverns template design with the installation, reinforcement installation, concrete pouring of the concrete steps and precautions in detail; bored pile and the underground cave has proven before the construction of the shifting process.
