| 摘 要： | 针对当前滨海城市整治河道防洪能力核算过程中存在的河道断面形状不规则、需要考虑潮水顶托影响以及河道糙率难以准确选取等问题,在SWMM软件的基础上,结合灵敏度分析等相关方法,实现了河道防洪能力的科学核算。研究表明,该方法不仅是可行的,而且对提高城市河道整治的优化水平具有明显作用。

| Abstract: | The current calculation of river flood-control capacity in seashore city is facing many problems,such as irregular river cross-section,backwater tide,inaccurate roughness coefficient and so on.In order to solve the above problems,SWMM software,incorporating parameter sensitivity analysis,was used for scientific calculation of river flood-control capacity.This approach is feasible and also helpful to enhance the optimal level of urban river renovation. |
