海上岩溶地质大直径群桩基础钻孔施工病害处理

摘要

以大连星海湾跨海大桥为例，结合工程的特点，对该工程的岩溶地质类型进行了分析，着重探讨了大直径群桩基础钻孔施工病害的处理措施，为确保工程的施工质量提供了技术支撑。%Taking Dalian Xinghai Bay cross-sea bridge as the examole,the oaoer analyzes the karst geological tyoes of the oroject by combining with the engineering features,and mainly exolores the treatment measures for the drilling construction diseases of the large-diameter oile grouo foundation,so as to orovide the technical suooort to ensure the engineering quality.
