摘　　要：在复杂应力历史场地上建设自动化集装箱堆场存在沉降控制标准高与工后沉降预测困难之间的矛盾。分别采用不考虑前期固结应力的e-p(孔隙比-压力)曲线法和考虑前期固结应力的e-lg p曲线法进行沉降计算,并比对场地前期陆域形成、地基处理设计资料。结果表明,在超固结土地基中,e-lg p曲线法计算得到的工后沉降远小于e-p曲线法,且与前期资料推算得到的沉降量更为接近。采用e-lg p曲线法计算超固结地基沉降具有较好的指导意义,可为复杂应力地基背景的自动化集装箱堆场基础设计提供参考。There is a contradiction between high settlement control standards and difficulty in predicting post-construction settlement when constructing automated container yards on complex stress historical sites.We use the e-p(porosity ratio-pressure)curve method without considering pre-consolidation stress and the e-lg p curve method considering pre-consolidation stress for settlement calculation,and compare design data of land formation and foundation treatment in the early stage of the site.The results show that in the super consolidated soil foundation,the post-construction settlement calculated by the e-lg p curve method is much smaller than that calculated by the e-p curve method,and is closer to the settlement calculated by the previous data.The use of the e-lg p curve method to calculate the settlement of overconsolidated foundations has good guiding significance and can provide reference for the design of automated container yard foundations with complex stress foundation backgrounds.
