PPP模式下综合管廊运营风险识别

Identification of Operation Risk of Utility Tunnel under PPP Mode

随着城市化的高速推进,管廊迎来了井喷式的发展,但因管廊建设总体投资大(工程造价约为1.2亿人民币每公里),资金回报周期长,为了缓解财政压力,PPP模式被广泛应用。现阶段,PPP模式下综合管廊目的利益相关方对于管廊运营管理领域的研究相对较少,且研究的深度不足。参建各方的精力大多集中于工程的立项、建设期,而投入于管廊运营管理及运营风险识别应对方面的精力往往较少。现就管廊的运营风险,结合失败案例,进行初步的分析和识别,为管廊运营风险评价提供有效支撑,以便更科学地制定出合理的风险应对机制,提高此类项目成功实施的概率。

With the rapid advancement of urbanization,the utility tunnel ushers in a blowout development,However,due to the high overall investment in the construction of utility tunnel(about 120 million RMB per kilometer)and the long cycle of capital returns,the PPP model has been widely used to alleviate the financial pressure.At present,there is relatively little research on the operation and management of utility tunnel among stakeholders under the PPP model,and the depth of research is insufficient.The energy of all parties involved in the construction is mostly focused on the project proposal and construction period,and there is often less effort invested in the operation management and risk identification of utility tunnel.Combined with the failure cases,the operation risks of utility tunnel are preliminarily analyzed and identified in order to provide the effective support for the risk evaluation of utility tunnel operation,scientifically work out a reasonable risk response mechanism and improve the probability of successful implementation of such projects.
