结合CFG桩与碎石桩组合型复合地基处理可液化地基的工程实例,介绍CFG桩与碎石桩组合型复合地基的处理方法和方案比选,对组合型复合地基的加固机理进行分析,进一步优化设计方案和施工工艺,提高加固效果。施工结束后检测结果表明,处理后复合地基承载力显著提高,地基液化情况得到明显改善,同时施工成本相对较低,是处理可液化地基的有效技术措施。
Combining with CFG pile and gravel pile composite foundation treatment of liquefiable foundation engineering examples, introduces CFG pile and gravel pile combined composite foundation treatment methods and comparison of options, reinforced composite foundation of the reinforcement mechanism analysis, and further Optimize the design and construction process, improve the reinforcement effect. After construction, the test results show that the bearing capacity of the composite foundation is significantly increased, the liquefaction situation of the foundation is obviously improved, and the construction cost is relatively low, which is an effective technical measure for liquefiable foundation treatment.
