Abstract:

The core driving force is an important driving force to promote the rapid development of utility tunnel project. In order to effectively identify the structure and mechanism of core driving force of utility tunnel, a core driving force model of utility tunnel that includes a foundation layer based on realizable force, a core layer based on collaboration capabilities and a presentation layer is established based on analysis tools such as supply chain. The influencing factors for core driving force are listed based on the existing researches and expert interviews; and the influencing factors for core driving force are interpreted and summarized by factor analysis method. The empirical research results show that: The core driving forces of utility tunnel project consist of 11 key capacities, i.e. the operational management and profitability, all parties′ collaboration capability in the planning and construction period, engineering and materials management capability, strategic layout and technical support capability, financing capability, government relations and cooperation capability, risk response capability, capital operation capacity, capital supply capacity, all parties′ collaboration capability in the operation period and government regulation and control capability; and the scientific nature of the theoretical model is verified. The results show that cooperative force plays a core role in promoting municipal utility tunnel project. Under the premise of ensuring the realizable force, focusing on nurturing core driving force can solve the problems of slow progress of municipal utility tunnel project.
