State evaluation method for urban underground comprehensive pipe gallery

Abstract

The invention discloses a state evaluation method for an urban underground comprehensive pipe gallery. The state evaluation method comprises the following steps of analyzing a possibility factor of danger occurrence of the comprehensive pipe gallery, and analyzing an influence degree factor after the danger occurrence of the comprehensive pipe gallery; according to the possibility factor of dangeroccurrence of the utility tunnel and the influence degree factor after danger occurrence, carrying out hierarchical division on the possibility of danger occurrence and the influence degree after danger occurrence respectively; respectively calculating the comprehensive weight of the possibility factor to the danger possibility P1 and the comprehensive weight of the influence degree factor to thedanger influence degree P2 by adopting an analytic hierarchy process; carrying out expert scoring on each possibility factor and each influence degree factor, and respectively calculating a danger possibility P1 and a danger influence degree P2; and calculating a state comprehensive score R of the comprehensive pipe gallery by using the danger possibility P1 and the danger influence degree P2. The state evaluation method can perform comprehensive and systematic state evaluation on the comprehensive pipe gallery and is suitable for the practical engineering application.

Description

technical field [0001] The invention relates to the technical field of state analysis of comprehensive utility corridors, in particular to a state evaluation method for urban underground comprehensive utility corridors. Background technique [0002] The urban underground comprehensive pipe gallery integrates urban lifelines such as water supply, drainage, heat, gas and power cables into the comprehensive pipe gallery for centralized laying and unified management, which is conducive to improving the level of urban comprehensive management and service levels. As an extremely important lifeline project of the city, the urban underground comprehensive utility gallery can evaluate the status of the comprehensive utility gallery and grasp the status of the comprehensive utility gallery in real time, which can provide decision-making support for managers. [0003] During the operation of the comprehensive utility gallery and internal pipelines, under the dual effects of internal fa...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, there are few methods for evaluating the status of urban underground comprehensive utility corridors. According to literature research and retrieval, there are currently very few studies that identify the safety risks and influencing factors of comprehensive utility corridors based on the Kent method, and respectively construct Fault tree model, and established an evaluation system for some single risk accidents

However, in the prior art, there is a lack of a comprehensive and systematic state assessment method for the comprehensive utility gallery
