瞬时单位线法在江西省应用的探讨

Discussion on the application of instantaneous unit line method in Jiangxi province

瞬时单位线法在江西省得到广泛应用,为了在该地区更加合理地使用该方法进行水利工程设计,选取27个集雨面积大于50km^2且小于1000km^2的水文站作为代表站,通过对比分析各代表站瞬时单位线法和经验适线法计算的设计洪水成果,对瞬时单位线法在江西省应用的问题进行了研究分析,提出在利用瞬时单位线法进行工程设计时需综合考虑工程规模、重要性及地理位置等因素.该成果为瞬时单位线法在江西省地区的应用提供了依据.

The instantaneous unit line method has been widely used in Jiangxi province. In order to use the method more rationally in the area for the design of water conservancy projects,27 hydrographic stations with rain collection areas greater than 50 km^2 and less than 1,000 km^2 were selected as representative stations. By comparing and analyzing the design flood of the instantaneous unit line method and the objective estimate line method of each representative station,studied and analyzed the application of the instantaneous unit line method in Jiangxi province. In this paper,it is proposed that the factors of scale,importance and geographical location should be considered in engineering design. The results provide a basis for the application of instantaneous unit line method in Jiangxi province.
