Abstract
This invention discloses a model test device and method for curtain grouting and excavation of tunnels in high-temperature, water-rich and weak strata, comprising weak strata simulation system, working condition simulation system, curtain grouting system, and monitoring and data acquisition system. The weak strata simulation system is the main box used to fill the soft soil. The working condition simulation system includes a high geothermal simulation system, a water pressure simulation system with stepwise loading of water pressure and volume, and a three-dimensional confining pressure simulation system with stepwise controllable loading of confining pressure. The invention can realize the whole test process simulation of grouting reinforcement and excavation of tunnels in weak strata effectively under the action of confining pressure and geothermal heat, and it has a positive reference effect on actual soft stratum tunnel curtain grouting and safe excavation.
