摘要
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。
Because of the hydraulic fill has high water content,high compressibility and low shear strength,and also many problems,such as ground nonuniform settlement,deep pit excavation and corrosion of concrete and reinforced bars will be occurred when the large oil tank storage base being built on the offshore hydraulic fill.Based on practical project,the influence of differential settlement is analyzed using finite element method for neighboring oil tank foundation of vibro replacement stone column composite foundation,and the results are compared and studied between that of CFG piles and deep mixing piles,the results can be as references for the ground improvement design and construction of raw oil storage base.
