摘　　要：为了有效应对岩溶地区隧道排水系统结晶堵塞带来的渗漏水破坏问题,采用文献综述的方法总结了岩溶隧道排水系统结晶组成成分、机理及其影响因素,详细归纳了现有的结晶处治技术,阐述了各技术的研究现状,对各处治技术的发展进行了展望。结果表明:隧道内部的结晶成分以碳酸盐为主,其成盐离子主要来源于岩溶水以及混凝土中,该现象受到诸多因素的影响,并且各影响因素之间存在明显的耦合关系;现有的结晶处治技术种类繁多,在诸多场景均有良好的应用,但由于隧道排水系统属于隐蔽结构设施,各类技术在隧道结晶处治中的应用受到了极大的限制,并且由于隧道结构所处环境的复杂性,导致实际处治效果多数情况与理论存在较大差异。因此,针对隧道排水系统结晶处治技术的研究应从以下几点出发:明确各类处治技术的作用机理,加强多种技术协同作用的综合处治方法的研发;考虑隧道环境因素对实际处治效果的影响,增强各类处治技术对隧道排水系统应用场景的适用性;对岩溶地区隧道排水系统进行针对性设计,使其更加有利于结晶处治;加强后期运维管理,促进结晶预防-处治长效机制的形成。In order to effectively deal with the water leakage damage caused by crystallization blockage in tunnel drainage system in karst area,by using the method of literature review,the crystal composition,mechanism,and influencing factors of karst tunnel drainage system are summarized,the existing crystal treatment technologies are summarized in detail,the research status of each technology is expounded,and the prospects for the development of various treatment technologies are made.The result shows that(1)The crystalline components in the tunnel are mainly carbonate,and the salt-forming ions mainly come from karst water and concrete.This phenomenon is influenced by many factors,and there are obvious coupling relations among them.(2)The existing crystallization treatment technologies are various and have good application in many scenes.However,since tunnel drainage system is a hidden structural facility,the application of various technologies in treatment of tunnel crystallization is greatly limited.Moreover,due to the complexity of the environment in which the tunnel structure is located,there are significant differences between the actual treatment effect and the theory in most cases.Therefore,the research on crystallization treatment technology for tunnel drainage system should start from the following aspects:(1)Clarify the mechanism of various treatment technologies,and strengthen the research and development of comprehensive treatment method with the synergistic effect of various technologies.(2)Considering the influence of tunnel environmental factors on the actual treatment effect,enhance the applicability of various treatment technologies to the application scenarios of tunnel drainage system.(3)Specifically design the tunnel drainage systems in karst areas to make them more conducive to crystallization treatment.(4)Strengthen late operation and maintenance management to promote the formation of long-term mechanism of crystallization prevention and treatment.
