随着我国城市化进程的大力推进,高层建筑如雨后春笋般纷纷涌现!地面车流量也在逐年递增,城市地面道路承受越来越大的交通压力。为了显著改善城市地面交通拥挤不堪的现状,充分满足人们安全出行的需求,我国正在大力建设地下轨道交通系统。 With the vigorous promotion of the process of urbanization in our country, high-rise buildings have mushroomed in abundance. The flow of surface vehicles is also increasing year by year, and urban ground roads are subject to increasing traffic pressure. In order to significantly improve the current situation of urban ground traffic congestion and fully meet the needs of people’s safe travel, our country is vigorously building an underground rail transit system.
