摘　　要：随着进口原油量的增加,国内沿海地区需要建设大批量储罐(建筑在软土地基上);软土地基不经处理,不能满足储罐对基础承载力及沉降和不均匀沉降的设计要求。为提高软土地基的承载力,减少地基的沉降和不均匀沉降,将充水预压与充水试压相结合用于储罐地基处理,是一种经济高效的地基处理方法。A large number of tanks shall be built in China as the petroleum importation increases in recent years.Usually,tank foundations are built on soft subgrade with high compressibility and low bearing capacity.Prior to ground improvement,this soft subgrade cannot meet the design requirements of tank for soil bearing capacity,settlement and differential settlement.Therefore,different measures are taken to increase the soil bearing capacity and decrease both the settlement and the differential settlement.This paper introduces the application of ring-wall tank foundation and water-filling preloaded foundation in soft soil improvement.
