Research on water inflow risk assessment in water-rich fault tunnels

Le résumé fourni par la source

The timely prediction of water inflow risk grades during the construction of water-rich fault tunnels are of great significance to engineering risk control. Taking a highway tunnel in Gansu as a background, and based on on-site survey data, in-situ test data, and numerical analysis methods, evaluation method on the water inflow risk grade of the tunnel was explored. The results show that: (1) The prediction shows that the tunnel mileage with A, B, C, and D grades water inflow risks accounts for 0.0%, 1.1%, 4.9%, and 94.0% of the total length, respectively, and the risk of water inflow is low; (2) The prediction results of the Tunnel Water inflow Risk Grade Evaluation System (RPPMS1.0) under the influence of water-rich faults constructed based on the Analytical Hierarchy Process Principle (AHP) are consistent with the actual disclosure. The research conclusions of this article can provide scientific reference for water inflow risk assessment and prevention and control measures design in similar water-rich fault tunnels.
