摘　　要：由于岩体注浆的隐蔽性和不确定性,使得实际注浆工程在设计和施工过程中具有极大的盲目性,室内模拟试验成为研究其过程的主要途径。文章介绍了裂隙介质注浆基于是否考虑浆液黏度时变性假设的理论计算方法,阐述了在平板裂隙试验平台的基础上,开发利用裂隙网络注浆试验平台进行裂隙介质注浆室内模拟试验的重要性,介绍了注浆过程中浆液注浆扩散性能和加固效果影响因素的研究现状、注浆压力和被注岩体内部压力对浆液渗流规律的影响、渗透稳定性和堵水效果的研究进展,并对裂隙介质注浆模拟试验的未来研究方向进行了展望。Due to the concealment and uncertainty of rock mass grouting, the actual grouting engineering has great blindness in the design and construction process, and indoor simulation tests have become the main way to study its process. This article introduces the theoretical calculation method of grouting in fractured media based on the assumption of considering the time-varying viscosity of the slurry. It elaborates on the importance of developing and utilizing a fracture network grouting test platform for indoor simulation tests of fractured media grouting on a flat fracture test platform. The article also describes the research status of the diffusion performance and reinforcement effect influencing factors of slurry grouting during the grouting process, the influence of grouting pressure and internal pressure of the injected rock on the seepage law of the slurry, research progress on permeability stability and water blocking effect, and prospected the future research directions of grouting simulation tests in fractured media.
