Integrated corridor can reduce road excavation

save underground space resources and extend pipeline life. However

the huge cost of construction and operation fee has become the major constraints of the development of integrated corridor. A scientific method of charging is very crux to the development of integrated corridor. This paper takes account of the proportion of construction cost of ancillary facilities in pipeline corridor and the requirement of related ancillary facilities of pipeline based on the direct burial cost method and space proportion method. In order to calculate the comprehensive score and the adjustment coefficient of the auxiliary facilities

this paper adopts the analytic hierarchy process based on the standard segment with two cabins. The research results can provide some reference for the power cable in the operation and maintenance cost allocation of the comprehensive corridor construction.
