摘要 研究目的: 近年来城市轨道交通工程洪涝灾害频发,对防洪工程建设的研究越发迫切。本文通过识别轨道交通工程易受洪涝侵袭的薄弱环节,从总图布置、阻水及防淹、排水设施、水位监测及报警等方面提出一系列因地制宜的防洪工程建设思路。
研究结论: (1)轨道交通防洪工程应结合城市防洪治涝规划以及建设项目水影响评价报告的要求,因地制宜采取措施;(2)轨道交通工程线站位方案要将防洪需求纳入研究;(3)低洼区域隧道洞口和下沉广场应设置阻水挡水设施,并考虑足够能力的排水设施;(4)应配置洪涝灾情监测报警设施,为乘客和运营中心提供信息和决策依据;(5)本文研究可为轨道交通工程防洪建设提供指导。

Abstract：Research purposes: Recent years, floods and waterlogging disasters occur frequently in urban rail transit, it is very urgent and necessary to study the flood control project construction. By identifying the weak parts and risks of resisting flood disaster in rail transit engineering, this paper puts forward a series of flood control engineering construction ideas according to local conditions from the aspects of general layout, water blocking and flood prevention facilities, drainage facilities, water level monitoring and alarm.
Research conclusions: (1)The flood control engineering construction of rail transit shall take measures according to local conditions in combination with the requirements of urban flood control planning or water impact assessment report of construction projects. (2) The station location layout of rail transit project line shall incorporate the flood control demand into the scheme study. (3) Water blocking and retaining facilities shall be implemented, as well as the drainage pump facillity. (4) Weak nodes shall be equipped with flood and waterlogging alarm facilities to strengthen the monitoring and management of weak nodes for flood control, so as to provide information and decision-making basis for passengers and operation center. (5) The research result can be used as a reference and guidance for the flood control construction of subsequent rail transit engineering.

Key words： control flood layout flood prevention retaining wall(baffle) drainage facilities alarm facilities
