摘要
新建围涂工程的海堤顶高程是新建海堤工程设计标准的一个重要指标,而预留沉降是确保海堤在建成后是否达到设计标准的一个关键控制参数.以海盐东段围涂二期工程为例,选取了10个典型断面进行了分析计算和沉降原位观测,并进行了加载阶段划分,对该工程预留沉降的确定,从而使加载顺序和加载节点因素、堤身结构型式、设计标准等等有机结合,使沉降预留的确定更具安全性、经济性与合理性.
Seawall crest elevation is one of the important indicators in new reclamation engineering design, which is the key control parameters to meet the design standards of seawall construction. Taking the second sector of Haiyan reclamation pro- ject for example, 10 typical sections were selected for calculation and sedimentation in-situ observation, as well as the load- ing stage division, was conducted. The determination of reserved sedimentation for the project, organically combined with the loading sequence, the loading node factors, the seawall structure, and the design criteria, is benefit for the security, the cost and the rationality of the project.
