摘要
大连市三面环海,滨海相软土地基较为常见。软土的低承载力、低抗剪强度等特殊性质对建筑物地基危害较大,尤其是堤防工程的运用工况加剧了软土对其地基危害性。介绍了大连市某建于滨海相软土地基上的堤防工程采用振冲碎石桩法成功处理基础的案例,从工程地质条件、软土地基处理的方案选择、振冲碎石桩的设计、布置以及工程竣工检测结果方面进行了阐述,证实了振冲碎石桩法处理堤防软土地基是可行的,该方法技术可靠、经济合理、施工工期短、对提高地基承载力有显著效果,为相似工程设计和施工控制提供了借鉴。
Dalian is surrounded by sea on three sides with a lot of soft soil. Low bearing capacity and low shear strength, as well as other special properties of soft soil are harmful to the foundation of embankment. This paper introduces a successful case of processing soft foundation with vibro-replacement stone column at embankment projects in Dalian, and expounds the geological conditions in some embankment projects. The scheme of processing soft foundation, and the design and arrangement of vibro-replacement stone columns are also discussed. The test results further proved that the foundation treatment methods significantly increased the bearing capacity of soft foundation with feasible, reliable, economical, efficient results. It could provide reference to the similar engineering designs and constructions on foundation treatment.
