CFG桩复合地基承载力计算新公式研究
摘要:CFG桩复合地基作为一种用材经济、施工便捷、加固效果良好的地基处理手段,在工程实践中得到了广泛地应用。针对CFG桩复合地基的承载力计算,分析现行《建筑地基处理技术规范》JGJ 79—2012和《建筑地基基础设计规范》GB 50007—2011中在地基承载力计算方面存在的较大差别、复合地基承载力计算过于保守等问题;以传统太沙基地基承载力理论为基础并结合工程实践经验,提出先进行桩间土深度修正再进行复合的复合地基承载力计算新方法。
Abstract:CFG-pile composite foundation as an economy convenient effective ground handling means has been widely used in engineering field. For the calculation of bearing capacity of composite foundation of CFG pile, we analyses the not uniform on provision and too conservative on calculation about bearing capacity of composite foundation in Technical Code for Ground Treatment of Buildings and Code for Design of Building Foundation. Based on the theory of traditional Terzaghi and practical experience in engineering,propose the new method which correct the soil bearing capacity between piles firstly, then assemble the bearing capacity of pile and soil.
