在中国北方寒冷地区,温度低、雨雪量大等特殊环境,导致隧道拱顶出现渗水结冰的现象,在一定程度上破坏结构也影响行车安全.因此,如何针对这类冻害做出防治措施成为行业内重点关心的话题.人工、风力扫冰器以及融冰装置除冰技术等各类方式在很多工程维修养护过程中得到应用,但是基于寒区背景下,除冰技术在一些方案实施阶段中存在差异性.为此,文章首先分析比较3种除冰技术的特点,并结合实地案例,根据哈尔滨黎明大道公路隧道渗水结冰现象,对融冰装置的除冰效果进行实验分析,最终的分析结果和实验结论可为今后寒区隧道工程建设提供借鉴.

充填土料中粉粒含量对充填管袋的脱水性能影响较大,进而影响到管袋筑坝的施工周期.考虑袋体缝制方式对脱水特性的影响,在研究充填料含粉量对纵向吊袋脱水影响的基础上进行了横向吊袋脱水试验,研究5种不同级配下横向吊袋脱水量随时间的变化规律,并分析充填料含粉量与脱水速率之间的关系以及与纵向吊袋脱水试验结果进行对比分析.研究结果表明:横向吊袋的脱水过程分为稳定阶段和不稳定阶段,其中,稳定阶段为脱水过程的主导阶段,且该阶段内的脱水速率与脱水时间呈线性关系,在不稳定阶段中,脱水速率随时间略有波动,待吊袋内形成稳定的反滤结构
