近几年随着我国经济形势的发展,城市化进程不断加快,轨道交通建设的新一轮高潮已悄然形成。在新批准和在施的诸多轨道交通项目中以下三条线路十分引人注目,他们是广州三号线、大连三号线和天津的津滨线。这三条线路尽管他们地域跨度很大,修建形式也不尽相同,但他们共同表现出了与以往若干条铁路有着显著不同的几个重要特点,值得我们研究和借鉴。 In recent years, with the development of the economic situation in our country and the acceleration of urbanization, a new round of climax in the construction of rail transit has quietly taken shape. The following three routes are striking among the newly approved and underway rail projects: Guangzhou Line 3, Dalian Line 3 and Tianjin Binjiang Line. Although these three routes have very large geographical scope and different forms of construction, they have jointly demonstrated several important features that are significantly different from those of the past and deserve our study and reference.
