城市轨道交通工程具有投资大、周期长、风险高、效益低等诸多特点,而原有城市轨道交通建设模式已经无法适应社会需求,于是出现了新形势下BT模式。在现阶段,我国城市轨道交通建设纷纷采用BT模式,但是在实施过程中仍然存在许多有待解决的实际问题,即采取优化措施迫在眉睫。因此,本文深入分析了BT模式下的城市轨道交通建设,指出了优势与不足,同时提出了最基本的完善措施。
The urban rail transit project has many characteristics such as large investment, long cycle, high risk and low efficiency. However, the original mode of urban rail transit construction has been unable to meet the needs of society, so the BT model under the new situation appears. At this stage, the BT mode has been adopted in the construction of urban rail transit in our country, but there are still many practical problems to be solved in the implementation process, that is, it is imminent to take optimization measures. Therefore, this article deeply analyzes the construction of urban rail transit under BT mode, points out the advantages and disadvantages, and at the same time proposes the most basic perfecting measures.
