摘　　要：为通过热流体的能量传递来达到融雪化冰的目的,水热式融雪技术在预先埋设的管道内通入作为传热载体的循环热流体。针对山区高速的特殊路段,结合地理与气温环境情况,将可循环再生资源隧道温泉水作为山区高速桥面融雪的热源。在此基础上结合工程实例确定了漫排式水热融雪桥面系统的设计与铺设方案,并铺设了试验路。结果表明,对于一定环境条件下的桥面漫排式温泉水融雪系统,融雪效果良好。研究成果可以为采用水热式融雪化冰系统的路面及桥面铺装设计与施工提供指导。In order to achieve the purpose of deicing by transferring the energy of hot fluid, hydro- thermal snowmeh technology is to pass circulating hot fluid which act as a heat carrier into pre-planted pipes. This paper aiming at special sections of expressway in mountain areas and combining with the geo- graphical and environmental temperature conditions, studies tunnel mountain spring water, a kind of re- eyclable resource as a heat source for bridge deck snowmelt in mountain areas expressway. On this basis, the design and laying plan of diffuse hydrothermal snowmelt system were identified with engineering ex- amples, and the test road was laid. The results show that for this kind of snowmelt system at a certain en- vironmental conditions, the effect is good. The research results can provide guidance for the design and construction of pavement and bridge deck pavement with hydrothermal snowmelt system.
