摘要为研究裂隙岩体注浆过程中的浆液渗流–岩体变形耦合作用，自主研制可视化变开度裂隙注浆模拟试验系统。该系统主要由浆液供给设备、注浆模拟设备和数据监测设备组成，具有良好密封性且实现了注浆压力作用下裂隙开度变化，可模拟不同开度裂隙在注浆流量、浆液水灰比和侧向压力等多源因素影响下的浆液流动过程，并可用于气体渗流–岩体变形耦合作用机制研究。利用该试验系统开展浆液渗流–岩体变形耦合作用注浆模拟试验，结果表明：裂隙开度增加削弱了注浆压力对裂隙的扩张作用，使浆液在流动过程中的能量损耗减少；水灰比减小导致浆液渗流–岩体变形耦合作用显著增强；侧向压力增大导致浆液渗流–岩体变形耦合作用程度减弱。灰色关联分析法结果表明，影响浆液渗流–岩体变形耦合作用的因素敏感程度顺序为注浆流量＞侧向压力＞浆液水灰比＞裂隙开度。该试验系统的研制可为研究裂隙含水层注浆引起岩体变形等流固耦合问题和工程应用提供新的试验手段。

Abstract：To study the slurry seepage-rock mass deformation coupling effect during grouting in fractured rock mass，a visual fracture grouting simulation test system with variable fracture aperture was developed independently. This system included slurry supply equipment，grouting simulation equipment and data monitoring equipment. It had good sealing performance and achieved fracture aperture change under grouting pressure，and can simulate the slurry flow process under the influence of multi-source factors such as grouting flowrate，water-cement ratio，lateral pressure and so on. It was also can be used to study the mechanism of gas seepage-rock mass deformation coupling effect. A grouting simulation experiment was conducted using the system to investigate the slurry seepage-rock mass deformation coupling effect. The results showed that：the increase in fracture aperture weakened the expansion effect of grouting pressure on fracture plate，reducing energy loss during slurry flow，the decrease in water-cement ratio significantly enhanced the slurry seepage-rock mass deformation coupling effect，and the increase in lateral pressure weakened the degree of slurry seepage-rock mass deformation coupling effect. The results of grey correlation analysis showed that the order of factors affecting the sensitivity of slurry seepage-rock deformation coupling effect was grouting flow＞lateral pressure＞slurry water-cement ratio＞fracture aperture. The development of this test system provides a new method for studying fluid-structure interaction and engineering applications of rock mass deformation induced by grouting in fractured aquifers.
