BOT模式城市隧道项目中期评估方法的研究

A Mid-Term Evaluation Model for Build-Operate-Transfer Urban Tunnel Project

BOT模式项目宜每2年进行1次中期评估,而国内针对BOT模式大型桥隧设施的中期评估大多以政府监管部门主观考核的方式进行,随意性大且无法全面反映项目中存在的问题,故提出一种针对BOT模式城市隧道的中期评估方法,以杭州市庆春路过江隧道为例,将BOT模式城市隧道项目评估体系分为BOT协议评估、BOT企业评估、隧道设施运营状况评估、政府监管评估4个一级指标,每个一级指标又分为若干个二级指标,建立该BOT模式评估体系的层级结构,并运用模糊综合评估法对该BOT模式隧道进行评级。运用该方法对BOT模式城市隧道的评估得出的结果客观合理,可为类似的BOT项目评估提供参考和指导。

The mid-term evaluation of build-operate-transfer(BOT)projects should be conducted biennially,whereas the mid-term evaluation of large-scale bridge and tunnel facilities in China is mostly conducted using the subjective evaluation of government regulatory departments,which is arbitrary and can not reflect the problerms existing in project operation.Therefore,in this study,a mid-term evaluation model for BOT-mode urban tunnels is proposed,considering the Qingchun Road tunnel in Hangzhou as an example.The proposed model is divided into four first-level indices:BOT agreement evaluation,BOT enterprise evaluation,tunnel facility operation status evaluation,and government supervision evaluation.Each first-level index is further divided into several second-level indices.As such,the hierarchical structure of the BOT model is established.The fuzzy comprehensive evaluation method is adopted to grade the Qingchun Road tunnel.Objective and reasonable results have been obtained using the proposed model to evaluate the Qingchun Road tunnel;hence,this study can provide reference and guidance for the evaluation of similar projects.
