软土地基工后沉降是一个十分重要的土工问题，尤其是在港口、机场等项目中显的尤其重要。众多研究中，对于大型港口地基，通过实测沉降资料进行模拟分析的研究还相对较少。洋山深水港作为我国的重要港口枢纽，对于我国的港口贸易发挥着不可估量的作用。建成以来，对洋山港的工后沉降问题的研究以及对其今后的沉降预测、后续工程的沉降分析很少。本文正是通过收集洋山深水港一期工程四个实测沉降点的实测沉降资料，运用ORIGIN软件，对不同地质条件下的实测地基沉降进行了指数模型回归分析，来求得较为精确的指数模型参数。

Post-construction settlement of soft soil foundation is an important geotechnical problem, especially in ports, airports and other projects. There are relatively few researches about simulation analysis of the measured settlement data of large port foundation. As China's important port hub, Yangshan deep-water port plays an inestimable role in China's port trade. There are few researches on the post-construction settlement and settlement prediction of Yangshan port since it was built. In this paper, by collecting the measured settlement data of the first phase of Yangshan deep-water port, uses ORIGIN software for the exponential model regression analysis of the measured foundation settlement under different geological conditions, to obtain accurate index model parameters.
