摘　　要：上海某10×104m3油罐为国内同容积罐中首次建造在软土地基上的大型油罐,采用了碎石桩、塑料排水板及充水预压综合地基处理方案。实践表明,充水预压过程中使用应力路径法控制地基稳定是一种行之有效的监测手段。A storage tank with a large capacity of 100,000 steres has firstly been built on soft clay base in Shanghai China. Working on it by a comprehensive ground treatment, such as sand-gravel pile, plastic drainage plate and filling and prepressing, during the process, the method of stress path is practical and effective in monitoring and controlling the stability of the foundation.
