Abstract：

In order to study the evolution process and failure characteristics of water inrush in Karst tunnel under， high-geostress and high hydraulic pressure，a model test system for water inrush in high-geostress and high hydraulic pressure tunnels was developed，the testing system composed of a geostress loading system，a hydraulic loading system，a multiple information monitoring system and a main box. The main features of the system can provide both high-geostress and high hydraulic pressure，the geostress loading system can provide peak pressure to 1 000 kN and hold pressure for a long time，the hydraulic loading system can provide maximum hydraulic pressure to 50 MPa and the hydraulic gradient can be controlled. In addition，the main box is an integral frame structure，high bearing strength，good tightness，visualization；the reaction frame can slide left and right，and the test space is enlarged；the all parts are connected by high strength bolts，high scalability；multiple information monitoring system can be used to collect the test data in real time. In the YK7+400–YK7+445 section of Xiema tunnel was taken as an example，the solid-fluid coupling similar materials were developed independently，the water inrush model test of karst cave in front of working face of high-geostress and high hydraulic pressure tunnels was designed，the experimental data were analyzed and summarized，the spatio-temporal change rules of stress field，displacement field and seepage field of tunnel surrounding rock under the complex geological conditions were revealed，the information of water inrush in tunnel were mastered. Test results showed that the system was stable and reliable，the research methods and results will instruct similar engineering.
