摘要
结合上海市某大型集装箱码头建设项目,对大面积荷载作用下港区堆场的软土地基沉降进行动态监测,针对实测沉降-时间关系曲线的变化特点,引入双曲线模型对地基沉降进行非线性回归分析。通过预测值与实测值的对比分析证明双曲线模型的可靠性,在此基础上对地基最终沉降作出了预测,为港区的安全运营提供了指导。
Based on a harbor construction project in Shanghai,the post-construction ground settlement induced by large-area load is timely monitored.According to the shape of measured settlement-time curves,the hyperbolic model is used to fit the settlement data.The results of the comparison of ground settlement between predicted values and measured values verify the feasibility of hyperbolic model, and the final settlement of the ground is also predicted by hyperbolic model.
