Study on the Calculation of Foundation Deformation by Dynamic Compaction for the Intelligent Container Terminal in the Tianjin Port

本文采用理论分析、室内试验和现场试验相结合的方法,结合已有研究成果,研究了强夯法后软粘土地基变形计算的方法。本文提出了针对强夯法加固后形成的硬壳层地基变形计算公式,并根据天津港地区北港池欧亚北侧地块场地的工程实例,验证了该方法的可行性以及有效性。研究结果表明:在等效前期固结压力概念的基础上,本文提出并完善了强夯后地基的变形特性和后期沉降的计算方法,并结合周边工程的观测结果对本文结论进行了验证。

In this paper,the computational method on deformation of saturated soft soil foundation treated by dynamic compaction is studied with theoretical analyses,laboratory and field tests.The computational formula for deformation of the upper hard crusts after dynamic compaction is derived,which is verified feasible and valid by the fact at the north land area of OuYa,North Harbour Basin in the Port of Tianjin.The results show that the methods of measurements on deformation characteristics and residual settlement of the saturated soft soil foundation by the dynamic compaction are improved based on the.The methods are verified by the observation results of peripheral port constructions.
