在大面积浅海吹填软弱场地上建造大型原油储备基地,吹填土地基土体含水量高、压缩性大、抗剪强度低,存在地表不均匀沉降、深基坑开挖、混凝土和钢筋的腐蚀等诸多问题。该文依托实际工程,使用有限元方法,分析了振冲碎石桩复合地基上的相邻油罐地基不均匀沉降的影响,并与CFG桩、深层搅拌桩复合地基的计算结果进行了对比分析研究,为原油储备场地地基处理设计与施工提供参考依据。
The large-scale crude oil reserve base is constructed on the soft-fill site with large area of shallow sea. The foundation of the dredged fill soil has high water content, high compressibility, low shear strength, uneven surface settlement, deep foundation pit excavation, concrete and steel bar Corrosion and many other issues. Based on the actual project, the finite element method is used to analyze the influence of the uneven subsidence of the adjacent oil tank foundation on the vibro-replacement stone column composite foundation. The results are compared with those of CFG pile and deep mixing pile composite foundation Research, provide a reference for the foundation design and construction of crude oil reserves.
