摘要
公路隧道工程的建造成为了提高人们出行便利的重要途径,但隧道渗漏一直是个质量通病。通过调查发现,北方寒冷地区由于低温时间较长,隧道渗水处出现很多涎流冰,严重影响交通安全。由此可见,尽早地对路隧涎流冰产生的危害做出预防,具有很大的必要性。为此,文章针对研究对象进行实地考察,并结合数据分析,总结路隧涎流冰在不同条件作用下的形态特征。主要是考虑结构强度、气候变化、防排水系统和施工处理等方面的影响,指出:①渗水是造成涎流冰现象频繁发生的基础,其中地表水和地下水的汇流,为冰体发育提供物质基础;②根据数据分析,发现涎流冰形成的温度条件在0℃以下,温度的变化也是成冰的关键因素之一;③基于现有的工程技术,进行多方面的优化,才是解决寒区隧道结冰病害的高效防治措施,研究结果可供类似病害治理借鉴。
The construction of highway tunnel has become an important way to improve people's travel convenience,but tunnel leakage has always been a common quality problem.Through investigation,it is found that due to the long time of low temperature in the cold area of northern China,there is a few of icicle in the water seepage area of tunnel,which seriously affects traffic safety.It can be seen that it is very necessary to prevent the harm caused by the ice flow in the road tunnel as soon as possible.Therefore,according to the field investigation of the research object,combined with data analysis,this paper summarizes the morphology characteristics of the sliver ice flow of the road and tunnel under different conditions.It is mainly to consider the influence of structural strength,climate change,drainage system and construction treatment,etc.,indicating that:①Water seepage is the basis for the frequent occurrence of salivary ice,in which the confluence of surface water and groundwater provides the material basis for the development of ice bodies;②According to the data analysis,it is found that the temperature condition of the formation of salivary ice is below 0,and the change of temperature is also one of the key factors for the formation of ice;③Based on the existing engineering technology,multi-faceted optimization is the effective prevention and control measures to solve the icing disease of tunnels in cold regions.The research results can be used for reference in the treatment of similar diseases.
