切割水位过程线法在推求苏州河潮量中的应用

Application of The Method of Cutting Water Level Hydrograph in Calculating tidal volume of Suzhou River

闸门对过闸潮量的影响较大,使原有的水位流量关系发生了较大变化,影响水文站对潮量的推求。浙江路桥水文站是苏州河的潮量测控站,负责测量苏州河汇入黄浦江的代表潮量。但苏州河水闸独特的型式、灵活的调度方式以及闸门不定时的启闭,给苏州河潮量的推求造成了极大困难。历年来,苏州河没有一个可行的方法来推求出具体的潮量。经计算表明,切割水位过程线法是解决河流受水工建筑物影响,推求出苏州河潮量的一种较为可行的方法。

Hydraulic structures took particularly severe impact on the trend of the gate, then the original water flow relationship had been greatly influented the amount of Deriving hydrological station on the tide. Zhejiang Road River Bridge hydrological station is traffic controllers of Suzhou River, which are responsible for measuring the Suzhou River＇s empties into the Huangpu River on behalf of the tide. But Suzhou River sluice unique structure, flexible scheduling and timing of opening and closing the gate does not give the Suzhou River tidal volume Deriving which caused great difficulties. Over the years, the Suzhou River is still without a viable way to invert the specific tidal volume. The calculations this paper show that the process of cutting water line method is to solve the rivers affected by hydraulic structures, invert the Suzhou River, a tidal river volume is more feasible.
