粉细砂夹层的软粘土上建造大型油罐

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。

Study on Large Tanks on Soft Clay Strata With Silt or Fine Sand Seams

There are many large oil tanks located on soft clay strata along the coast and constructed during recent decade. Investigation and analysis of field measurement results and performance of several large tanks, also reference to construction experience in other countries, guidelines for control tank foundation stability and allowable differential settlements related to settlement types of the tank foundation were suggested. Also suggested was the value of lateral earth pressure coefficient concerning the ringwall.
