大型油罐软土地基的稳定与变形问题是工程设计中急待解决的重要课题。本文结合我们近十几年来在沿海地区所进行的大型油罐软土地基试验研究工作,通过对油罐充水预压期间所作的多种项目的实测资料进行分析研究,并参考国外有关资料,提出对油罐地基稳定控制方法,根据油罐地基沉降三种不同模式给出其不均匀沉降容许值及环基侧压力系数建议值。
The problem of stability and deformation of large-scale oil tank soft soil foundation is an important issue to be solved in engineering design. This paper combines the experimental research of large-scale oil tank soft soil foundations conducted in the coastal areas over the past decade, and analyzes and researches the actual data of various projects made during pre-pressing of oil tanks, and refers to relevant foreign data. A stability control method for oil tank foundation is proposed. According to three different modes of settlement of oil tank foundation, the differential settlement allowable value and the recommended value of pressure coefficient on the ring side are given.
