摘　　要：为进一步解决交通设施的渗漏问题,并探究不同止漏材料在不同渗漏条件下的适用性。首先对目前常用的基础设施止漏材料进行比选,分析不同条件下止漏材料的性能与要求;对交通运输基础设施渗漏的漏量大小、漏水位置进行分类,并分析其针对性治理方案。结果表明,随着漏水量、漏土量的增加,其止漏材料选取方案应有所不同,当渗漏仅引发结构病害时,可以使用常规凝结材料;而当形成漏水漏砂时,止漏材料需具备早强、速凝和抗高水压等特点。建议根据不同漏点水压、漏水量研发针对性高性能止漏材料,对于提升交通运输基础设施耐久性与韧性具有重大意义。In order to further solve the leakage problem of traffic facilities,and to explore the applicability of different leakage-stopping materials under different leakage conditions.Firstly,the commonly used infrastructure leakage-stopping materials were compared,and the properties and requirements under different conditions were analyzed.Besides,the leakage amount and location of transportation infrastructure leakage were classified,and the specific treatment schemes were discussed.The results show that with the increase of water and soil leakage,the efficient leakage-stopping material and scheme is different.When the leakage only causes structural diseases,the conventional condensation material can be used.When the leakage of groundwater and sand occurs,however,the leakage-stopping material should have the properties of high early strength,quick coagulation,and high pressure-resistance ability.It is suggested that targeted high-performance leakage-stopping materials should be developed according to the water pressure and water leakage at different leakage points,which is of great significance for improving the durability and toughness of transportation infrastructure.
