江南海涂围垦工程海堤沉降检测结果的分析及应用

Analysis and Application of the Detection Results of Seawall Settlement in Jiangnan Reclamation Project

随着围垦工程逐渐从沿岸向浅滩甚至浅海深入,围垦工程海堤的实际沉降相比以往是越来越大,如果仍然沿用沿岸工程的经验预估沉降量,常常导致合同纠纷。作者以苍南县江南海涂围垦工程为例,采用钻探结合抛石的方法对海堤抛填块石底界面进行测定,并分析海堤沉降原因,提出解决办法,供类似工程参考。

With the recent development of the reclamation engineering from the shallow water to the deep water,the traditional empirical approach may underestimate the foundation settlement of the seawall,which may cause contract disputes. The present paper combines the detecting method of the drilling and exploration,in order to determinate the boundary of the riprap seawall. Based on the results,the authors investigate the cause of the subsidence,and further propose the solutions. This study takes the Cangnan Jiangnan polder project as an example,and it can be a reference for other similar projects.
