Abstract：
Proper evaluation and correct selection of the waterproofing and drainage types for metro tunnels is an
effective way to reduce water leakage during tunnel operation. Regarding selection of waterproofing and drainage patterns, normally a single evaluation factor of water inflow is used for evaluation and analasis instead of comprehensive evaluation system. Based on previous studies of waterproofng and drainage of metro tunnels, an AHP-based judgement system for types of waterproofing and drainage is put forward, a mathematical evaluation model of the analytic hierarchy process is established, weights of the hierachy index affecting influential factors of waterproofing and drainage in metro tunnels are determined, and quantification of the types of waterproofing and drainage is achieved with established criteria and standards. Practical cases show that the fuzzy synthetic evaluation method is consistant with the actual situation. Further study and verification are required for this application using a concrete project.
