Abstract

This paper develops an indicator system consisting of three criterion layers and 13 specific indicators. This indicator system can be used for water resources utilizability evaluation during subway construction in water-rich weakly consolidated formation. The weight of each index is determined by using Delphi and G1 methods, and the assessment criteria is constructed according to related standards, specifications and the practice of Chengdu subway construction. Jiulidilukou station of Chengdu Metro Line 7 is selected as a case study, and the results show that its water utilizability during the construction is excellent, which indicating that the water pumped from aquifer should be reused after some proper measures instead of wasting of water resources.
