合理确定排涝泵站规模的感潮河道模型试验研究
Physical Model Test on the Scale of Drainage Pump Station on Tidal River
摘要
Abstract
Determining the optimal scale of pump station is a crucial aspect of designing drainage systems in tidal rivers.We constructed a physical model of a tidal river system and conducted experimental investigations on the scales of two pump stations situated at the outlets under selected hydrological boundary conditions and project opera-tional requirements.Our study reveals that:(a)constrained by the river's discharge capacity,a critical scale exists for the pump station,beyond which the water level remains unaffected by further scale increments;(b)the extent of water level reduction due to drainage pumping correlates closely with the proximity of the pump station,with greater proximity resulting in more pronounced water level drops.Building upon these insights and conducting multiple tri-als,we propose an optimal scale combination for the two pump stations to meet design specifications:80 m3/s for the Wenchong Pump Station situated farther away,and 130 m3/s for the closer Jinzichong Pump Station.This re-search offers valuable data for optimizing design processes and serves as a reference for similar projects.关键词
