某大型原油储库地基处理设计原计划采用振冲碎石桩复合地基,但存在质量控制困难、工期较长等因素影响,加固效果不理想,达不到设计要求,根据场地和施工技术条件,确定采用CFG桩复合地基处理方法。考虑油罐地基处理方案的重点在于地基的承载力、变形,尤其是不均匀变形,通过对场地条件的分析,按强度和变形双重控制理论进行了设计。工程试验表明,在本场地所采用的复合地基设计方案是合适的,可作为同类工程借鉴。

The original plan is to use vibro-stone column composite foundation to treat a large oil tank foundation.The result of strengthening is not satisfactory because of some factors,such as difficulty to control quality and long construction period etc.Treated ground can not meet the design requirements.The key in treatment design of tank foundation lies in bearing capacity and deformation of foundation,especially in non-uniform deformation.Through the analysis of site conditions,composite foundation of CFG piles is adopted and designed according to strength and deformation of dual control theory.E...
