基于水力模型的深层调蓄隧道系统提标方案优化

Optimization of Upgrading and Reconstruction Plan of Drainage System of Deep Tunnel Based on Hydraulic Model

《上海市城镇雨水排水规划(2020-2035年)》规划新建苏州河深层排水隧道工程,服务苏州河沿线25个排水系统,实现防汛能力提高和污染物减排的双重目标。以芙蓉江排水系统为例,针对不同的规划方案,以排水管网水力模型为研究工具,分析不同方案中各接入口的服务范围以及积水面积、积水路段等指标。结果表明,接入口位置对深隧提标功能的发挥影响显著,制定方案时应力求各接入口服务范围相对均匀。制定方案时,可利用水力模型工具分析不同位置接入口的实际服务面积,同时,根据不同指标分析各方案的提标效果,提出推荐方案以实现工程目标,并发挥最大工程效益。研究成果可应用于深层调蓄隧道规划方案设计,研究思路也可为类似工程的方案制定提供有益参考。

Shanghai Urban Raimvater Drainage Plan(2020-2035)plans to build a new Suzhou River deep drainage tunnel project to serve 25 drainage systems along Suzhou River,achieving the dual goals of improving flood control capacity and reducing pollutant emissions.This study took Furongjiang drainage system as an example.According to different planning schemes,hydraulie model of drainage pipe network was used as a research tool to analyze the service scope of each inlet in different schemes,as well as water pooling area and stagnant water section of different schemes.Results showed that the location of access port had a significant impact on function of deep tunnel to improve the standard.W hen formulating the plan,service range of each access port should be relatively uniformn.When formulating a plan,hydraulie model tools could be used to analyze actual service area of access points at different lo-cations,and at the same time,to analyze the effect of each plan according to different indicators,and to propose a recommended plan to achieve project goal and maximize project benefits.Results of this research can be applied to planning scheme design of deep stor-age tunnels,and research ideas can also provide a useful reference for formulation of similar projects.
