上海地下交通设施防洪调查

Investigation on Flood Control of Traffic Facilities in Underground Spaces in Shanghai

为了缓解地表交通压力,越来越多的城市利用地下空间修建交通设施,如地铁、隧道、地下车库等,这不仅扩大了土地利用维度,还可以带动商业的发展。然而由于自身结构等特殊性,地下空间防洪问题面临着很大的挑战。作者结合国内外地下交通设施建设情况以及以往的洪水灾害,对上海轨道交通线路中三条主要地下路线进行实地考察,调查了各出入口的外观形式、楼梯构造、落水槽和防汛墙板等防洪设施,并针对现存不足,提出了一些对策与建议。

In order to alleviate the ground traffic pressure,in more and more cities some traffic facilities have been constructed in underground space,such as MTR,tunnels and underground garage.It not only expands the dimension of land utilization,but also promotes the development of commercial activities.However,due to its unique structures,the flood control in underground space is facing great challenges.Considering the situation of transport facilities in underground spaces both at home and abroad,and the previous underground flood disasters,field investigations of three main underground metro lines have been carried out in shanghai.The appearance of gateways,structures of staircases,waterspouts,flood control wallboards and other elements of flood control were observed.At last,for the existing inadequacy of the facilities,some proposals were given.
