石油储罐试压及运行过程中出现不均匀沉降将导致罐体倾斜，严重影响储罐的安全运行，因此石油储罐基础对地基承载力的要求十分严苛。石油储罐地基处理通常做法有桩基础法、强夯法、换填法等。对粒径0~40 mm路基碎石换填在石油储罐地基改良中的应用进行了研究，给出了适用范围，换填的宽度和厚度，施工要点等。通过实例数据说明粒径0~40 mm路基碎石能满足较高地质条件的换填需要。
The uneven settlement occurred in the pressure test and operation of oil storage tank would in-duce the tilt of tank, which seriously influenced the safe operation of the oil tank; therefore, there was a severe requirement for bearing capacity of the tank foundation. Pile foundation method, dynamic compaction method and replacement method were commonly used in foundation treatment of oil storage tanks. In this paper, the application of 0 - 40 mm subgrade crushed stone in the foundation replacement of oil storage tank is studied; the scope of application, the width and thickness of replacement and the key point of construction are described. Data of practice are given to indicate that the application of 0 - 40 mm subgrade crushed stone can meet the needs of replacement under higher geologic conditions.
