英文摘要：
According to the research status and the existing problems of fluid-solid coupling model test, the key technical problems of water inrush modeling are discussed and the fluid-solid coupling model experiment system developed. A new similar material for solid-fluid coupling is developed through massive proportioning tests. The material is mixed with sand, talc powder,paraffin, and hydraulic oil. Sand and talc powder are aggregate, paraffin a cementing agent, and hydraulic oil a regulator. Extensible test bench is developed by PVC material with high strength, which can automatically generate underground river, aquifer, karst cave, dissolved chamber, and other geological defects. Meanwhile, the monitoring system for water inrush precursor is developed by fiber bragg grating, which has a good synchronism and comparability of information obtained for realizing real-time acquisition and analysis for the information of stress, displacement, seepage pressure, temperature, microseism, and so on. Model test of water inrush in roadway is carried out by the experiment system, showing that the experiment system with high stability and reliability can be widely used for the model test of fluid-solid coupling problems for underground engineering.
