隧道及地下工程在城市交通中的运用

当前城市交通紧张情况十分突出,已成为我国城市建设必须解决的重要课题。借鉴国内外经验,在大城市应适当考虑修建地下铁道;有的城市在一定的地形和自然条件下,可在必要地点修建公路隧道;在车流密度较大的道路交叉点应考虑修建必要的地下通道;有条件的城市还可适当修建地下街以缓解地面交通的紧张状况。为解决机动车辆大量增加后,停车场地不足,在一些大型公其活动场所可适当修建地下停车场。

Application of Tunnel and Subway Engineering in urban Transport System

At present the extraordinarily tense urban traffic has become a very much pending issue yet to be settled. Referring to the experiences home and abroad, it shonld be well considered to build underground railroads in big cities. If the natural terrain condition permit, the shunting tunnels can be built at appropriate points in some cities, At the crossings of heavy traffic, it is necessary to consider the construction of subway passage, In some cities with available couditions, even the underground streets construction can also be taken into account jn an attempt to ease up the strained situation of the surface traffic, with the ever increasing in the number of motor-driven vehicles, it will be short of parking places for the large-scaled public places, in which case appropriate consideration should be made to build underground parking places.
