碎石桩复合地基在处理可液化地基中的应用

摘要

The underground geological condition of Panjin City Sports Center shows that ,in the range of 14 meters underground exists silt mixed with silty clay soil ,which ,under seismic loads ,will produce sand liquefaction phenomenon .In response to this situation ,gravel col-umns composite foundation is used for processing .After processing ,liquefaction foundation is basically eliminated ,and the bearing capacity can also meet the requirements .After completion ,the project runs in good condition .%盘锦市体育中心地质情况表现为在地下14 m范围内存在粉砂夹粉质粘土土层，在地震荷载作用下，将会产生砂土液化现象。针对这一情况，采用了碎石桩复合地基进行处理，处理后地基液化现象基本消除，地基承载力也满足要求。工程完工后，运行情况良好。
