浙江沿海堤坝工后沉降调查及分析

通过对浙江沿海堤坝沉降数据的监测,分析了堤坝工后沉降预留值的计算方法以及常用拟合方法存在的不足,进一步完善沉降优化组合拟合分析方法,提高工后沉降估算的精确度。结合工程实例,把优化组合的拟合模型结果与实际沉降的发展情况进行比照,拟合结果良好。优化组合方法可用于海堤工后沉降规律分析。

Investigation and analysis on post-construction settlement of coastal levees in Zhejiang Province

Through the monitoring on the settlement data of the coastal levees in Zhejiang Province， the defects of the calculation method and the conventional fitting method for the reserved values of the post-construction settlement of the levees are analyzed herein; and then not only the fitting analysis method for the optimized integration of the settlement is further improved， but the accuracy of the estimation on the post-settlement is also enhanced. Combined with an actual engineering case， a contrast between the result from the fitting model for the optimized integration and the development of the actual settlement is made and a better fitting result is obtained as well. Generally， the method of optimized integration can be applied to the analysis on the post-settlement law of coastal levees.
