采用灌浆材料对引水隧洞施工中不良地质体进行超前预处理，是突涌水等地质灾害预防和治理的有效手段，然而在高压大流量动水条件下，超前预处理灌浆材料无法满足现场需求，迫切需要提高其动水工作性能。作为常用的超前预处理灌浆材料，水泥基多从抗分散能力、力学性能和可灌性等方面进行改进，如在水泥中添加抗分散剂和矿物掺和料，研发新型水泥等；聚氨酯材料多从提高其动水留存率和材料力学性能与微观结构演变关系等方面改进；环氧灌浆材料的研究着重于提高其对低渗性岩体的浸润渗透性，近年来超吸水聚合物也引起研究者的兴趣。本文综述近年来引水隧洞施工中针对突涌水处理常用的超前灌浆材料最新研究成果，从特种水泥灌浆材料的开发、遇水发泡聚氨酯力学强度的提升、在动水条件下环氧浆液的固化等方面展望引水隧洞超前预处理灌浆材料未来的发展方向。

Most headrace tunnels are in high mountains and valleys with complex hydrological and special geological conditions. During the construction of the headrace tunnel, water inrush often occurs when suffering from unfavorable geological bodies. Pre-grouting is a significant technical means to prevent such occurrence of geological disasters. However, under the condition of high pressure and large flow dynamic water, the pre-treatment grouting materials can not meet the needs of the site, therefore it's of absolute importance to improve its dynamic water performance. Various inorganic grouting materials have been developed to realize high-performance pre-grouting, such as cement, microfine cement, and water glass, or organic grouting materials, such as polyurethane and epoxy. However, among the aforementioned grouting materials, cement hardening requires a long time, and epoxy and polyurethane are expensive. Besides, due to the high pressure, large flow rate, and rapid velocity water inrush environment, grouting materials face the issues of being washed out, diluted, and dispersed, resulting in difficulty of slurry condensation, low mechanical strength, and poor long-term water plugging effect of consolidated body. Therefore, improving the performance of pre-grouting materials under dynamic water conditions is urgent. Cement, polyurethane, and epoxy grouting materials have been commonly used for advanced pretreatment. Researchers have recently tried to improve the anti-scouring ability, mechanical properties, and durability of cement grouts by adding anti-washout admixtures, nanomaterials, and mineral admixtures to grout mix constituents. In addition, phosphate cement grouting materials have been developed to plug water quickly. Therefore, to promote the application of polyurethane grouting materials in ultra-high velocity dynamic water environments, hydroxypropyl methylcellulose has been added to water-soluble polyurethane slurry to improve its retention rate in flowing water. The relationship between density, mechanical behavior, and microstructure evolution of polyurethane has been researched. The time-varying effect of the permeability of epoxy slurry has become a focus when facing high-pressure and low-permeability geological bodies. In addition to commonly used pre-grouting materials, a superabsorbent polymer grouting material based on self-volume expansion by physical water adsorption has been developed. The latest research on cement, polyurethane, epoxy resin, and superabsorbent polymer grouting materials was reviewed. Based on this, the main problems requiring deep exploration in the future are recommended from three aspects: the development of special cement grouting materials, the development of polyurethane, which is low cost, foaming body with high strength, strong resistance to water inrush, and polyurethane-modified by inorganic materials.
