Cost allocation model of power pipeline access corridor based on group decision and spatial proportion method

Abstract

With the continuous acceleration of the urbanization process, more and more cities begin to lay down utility tunnels utility tunnels that can effectively improve the utilization efficiency of urban space. Based on this, this paper firstly studies the construction cost composition and operation and maintenance cost composition of the utility tunnels, and then, considering all stakeholders involved in the electrical cables into utility tunnels, establishes the allocation model of the electrical cables into utility tunnels cost based on the group decision model and the spatial proportion method. Finally, some sections of Qingdao utility tunnels are selected as examples for verification. The results show that the model has strong practicability and can effectively solve the problem of cost allocation of electrical cables into utility tunnels.
