江苏沿海地区防洪排涝工程潮型的优化设计
Optimum design for tide curve in flood protection and drainage project in Jiangsu coast area
摘要
Abstract
In order to optimize the design of hydrological parameters for flood protection and drainage project in coast area,based on Gumbel-Hougaard Copula function and conditional probability theory, the correlation characteristics between high tidal level and low tidal level in the same tidal process line were analyzed,then a new method for design tide curve was proposed.Based on this method,consi-dering three return period conditions(T=20,50,100,200 a),the design types of tide were given at Lianyungang,Sheyangzha and Tianshenggang tide gauges in Jiangsu province as examples.Comparing with same multiple enlarging method and the improved same multiple enlarging method,the new me-thod considers sufficiently the correlation characteristics between high tidal level and low tidal level, therefore,it is more perfect in theory;the tidal range from the new method is significantly larger than from other methods,and from a security standpoint,other methods have some design risks;the new method can also be extended to other similar design of combination of hydrological variables.关键词
