摘要
近年来因围海造地而实施的滩涂工程规模增大,但由于缺乏规划研究,极易造成洪水、内涝等问题。结合沿海滩涂工程水利规划实践经验,对浙江省围涂工程涉及到的防洪防潮和排涝标准、设计雨型和潮型、雨潮组合方式、围涂区水面率和河网密度、围涂区客水排泄等水利规划问题作了初步分析和总结。结果表明:浙江省的围涂工程的防洪标准总体适宜,排涝标准应适当提高;以围涂区水面率不低于12%的规定的基本合适;提出了处理围涂区客水承泄问题的措施,可供类似规划设计工作参考。
Combining with practical experience,we analyze the criterion of flood control,tide control and drainage,design rainfall and tide pattern and combination modes of tide and rainfall,surface water ratios and drainage density,guest water excretion in the reclamation area.The results show that criterion of flood control is generally appropriate,however,the criterion of drainage needs to be raised;the regulation that surface water ratios below 12% is basically reasonable.We put forward the measures for dealing with inflow and excretion of guest water,which provides useful experiences for similar projects.
