涵洞在高速公路的排水系统中具有极为重要的作用,针对国内高速公路涵洞结构安全性评估缺乏汛期的具体评估,未体现区域性,往往依靠经验来判定涵洞汛期安全隐患的现状,论文以深汕高速公路东段为例,进行了雨洪特点、水毁机理和养护资料分析,研究提出了高速公路涵洞结构汛期安全性评估指标及方法,研究成果可以更好地评价和预测高速公路涵洞的抗水灾能力,确保高速公路的安全运营。
Culverts play an extremely important role in the drainage system of expressways. In view of the lack of specific assessment of flood season safety assessment of highway culverts in China and the lack of regionalization, experience is often used to determine the current situation of potential safety hazards in culverts. In this paper, Taking the eastern section of the highway as an example, the characteristics of rainstorm, the mechanism of water damage and the analysis of maintenance data are studied. The indexes and methods of safety assessment for expressway culverts during flood season are proposed. The research results can better evaluate and predict the flood resistance of highway culverts Ability to ensure the safe operation of the highway.
