复杂水文条件下围涂工程的龙口合龙技术

Dike Closure Technology in Reclamation Project Under the Complex Hydrological Condition

多流域水系在围垦工程围区内汇合,增加了围垦工程龙口合龙施工的难度。以浙江省乐清市胜利塘北片围涂工程为例,探讨了上游复杂水文条件下龙口段高低潮沟处理、龙口保护的措施和龙口施工对上游排涝的影响,介绍了采用预测潮位过程优化龙口堵口的方法。

The construction difficulty of dike closure would be increased when multi-basin rivers are converged on the reclamation project area.Taking Shenglitang north reclamation project in Zhejiang Province as an example,the paper introduced technology and engineering measures dealing with high and low tide grooves and protecting the closure dike,analyzed the impact of construction on the drainage of the upper reaches,presented an optimizing method by forecasting tide process to the dike closure process.
