寒区隧道防寒设计与研究现状及发展
Research Status and Development of Cold-proof Design for Tunnels in Cold Regions
摘要
Abstract
In recent years,with the construction of"One Belt,One Road"and the westward shift of the transportation network in China,more and more tunnels in cold regions have been built in the western region.However,due to the frequent occurrence of freezing damage to tunnels in cold regions,cold prevention and thermal insulation is a diffi-cult problem to be solved during the construction of tunnels in cold regions.By reviewing typical cases of tunnel en-gineering in cold regions,the characteristics and causes of frost damage are summarized,the existing measures for waterproofing and drainage are summarized,as well as insulation measures around and at the openings.The ratio-nality and applicability of these measures are evaluated in order to provide reference for the frost heave effect and cold insulation design of cold region tunnels in future.关键词
