闽江口内沙浅滩整治方案

闽江口内沙浅滩是闽江通海航道浅滩段最长，水深最浅，碍航最为严重的沙质浅滩。二期整治要求水深达到-5．8m，乘潮通2．0万吨级海轮。文章主要介绍内沙浅滩整治工程方案物理模型试验研究成果与推荐方案实施后所取得的工程效果，并提出了继续增深治理应注意的几个问题。

Schemes to Regulate Sandy Shoal in Minjiang Estuary

The sandy shoal in the Minjiang Estuary is the longest and the shallowest sandy shoal in the navigational channels taking the Minjiang River to the sea ,hindering most grievously the navigation in the channels. It was spec- ified for the second phase of the regulation project that, after the regulation project is completed, the water depth in the navigational channels should be -5.8 m and seagoing vessels of 20 000 -dwt can sail through on high tides. The paper presents mainly the results of the physical model tests for the schemes to regulate the sandy shoals and the engineering achievements after the recommended scheme was implemented as well as some issues that should be given due consideration if further deepening of the channels is required.
