摘要
轨道交通隧道工程下穿河道或湖泊等水域时,相关规范仅明确必要情况下应设置防淹门,未规定具体情况下的指标。为规范国内关于防淹门的设置原则和标准,论文通过进一步解读规范,并结合国内现有轨道交通案例进行调研,分析各地不同河道深度、宽度、过水断面,工程造价、行车安全、灾害防控等工况下防淹门设置的基本原则和做法,对防淹门的选型要点进行总结。
when a rail transit tunnel project passes through water areas such as rivers or lakes,the relevant specifications only specify that flood prevention gates should be set up if necessary,without specifying the indicators under specific circumstances.In order to standardize the principles and standards for the setting oflood gates in China,by further interpreting the norms and combining with the investigation ofexisting domestic rail transit cases,the paper analyzes the basic principles and practices of setting flood gate under different river depth,width,water crossing section,engineering cost,driving safety,disaster prevention and control,and summarizes the key points of selection of flood gate.
