随着城市的发展,城镇居民和出行车辆日益增多,交通拥堵问题越来越严重,现有交通道路已无法满足需要,必须进行改造,例如:将原有的平面交叉改造成立交形式,立交形式主要有两种形式:上跨式高架桥和下穿式通道。由于土地资源、环境优美等多方面的考虑,当地政府、规划部门在城市道路建设中会选择下穿式通道立交形式。下穿式通道立交与上跨式高架桥排水相比更具复杂性和特殊性。
With the development of cities, urban residents and traveling vehicles are increasing day by day, and the problem of traffic congestion is becoming more and more serious. Existing traffic roads have been unable to meet their needs and must be rebuilt. For example, the original plan should be cross-transformed into an overpass type and an overpass type There are two main forms: the upper span viaduct and the lower passway. Due to various considerations such as land resources and beautiful environment, the local government and planning departments will choose the underpass type interchange in urban road construction. Underpass crossing interchanges are more complex and specific than the upper span viaduct drainage.
