摘要 以湖北黄冈市蕲春县龙泉国际新城深基坑支护工程为实例,针对基岩地层起伏不平,深基坑支护桩施工嵌固深度不足的问题展开研究,采用加长、加密锚杆及桩前土预留平台等措施,取得了较好的效果。同时根据工程实施过程总结分析了类似地层中搅拌桩、锚杆以及围囹的施工要点。 The retaining structures for deep excavation of Longquan International Park in Qichun County, Huanggang City of Hubei Province are taken for an instance. Owing to unsmooth bedrock formations, the problem of inadequate embedded depth of retaining piles in deep excavation is studied. Good results are achieved by using longer and more dense anchors, reserved soil platforms before retaining piles and other measures. Meanwhile, some construction points of mixing pile, anchor and confining prison in similar formations are summarized and analyzed according to the project implementation process.
