Abstract:

为了选择适合于隧道工作环境与交通条件的路面结构类型,提高隧道路面的使用性能延长使用寿命,在广泛调研的基础上,采用灰靶理论从整体刚度、耐久性、平整度、抗滑性能、耐磨性能、修复与重建难度6个方面系统地比较了水泥混凝土与沥青混凝土两种常用的路面结构类型在隧道内的适用性。分析结果表明,采用灰靶理论评判模型选择隧道路面结构类型在一定程度上克服了选择过程的主观因素,使隧道路面的选择结果更具有客观性;在隧道内特殊的工作环境与交通条件下沥青路面的性能更加优越,具有更好的适用性,能提高隧道路面抗滑性能,降低噪音,改善行车舒适性,维修、养护简便,保证隧道营运通畅,为实体工程路面结构类型选择提供依据。
