该文结出了圆形基础在竖向荷载作用下，碎石桩复合地基最终沉降量的数值计算方法和计算程序，能够快速方便地计算地基中附加应力分布和地基沉降曲线。并以天津某大型油罐为例进行了沉降计算，对沉降计算的经验系数进行了分析，其结论对今后油罐地基处理具有实际意义。 This paper presents the numerical calculation method and calculation program for the final settlement of composite foundation with gravel pile under vertical load, and can calculate the additional stress distribution and foundation settlement curve in the foundation quickly and conveniently. In addition, a large-scale oil tank in Tianjin was used as an example to calculate the settlement, and the empirical coefficient of settlement calculation was analyzed. The conclusion has practical significance for the future treatment of the tank foundation.
