摘　　要：隧道路面结构是整个隧道工程的重要组成部分,它对隧道的耐久性、保证行车安全、舒适性以及经济效益和社会效益有着极其重要的作用,是隧道工程建设中的一项关键技术。以宁淮高速公路老山隧道内路面结构为对象,采用通用有限元分析软件ABAQUS程序研究了隧道内半刚性沥青路面、水泥混凝土路面和连续配筋混凝土路面分别在路基或基层软化、路基或基层脱空以及路基沉陷等几种不利条件下的受力性能,并对不同类型隧道路面结构的初期造价进行了分析,根据分析结果,提出了老山隧道路面的合理结构形式。Pavement structure of tunnel is one of the most important parts of tunnel engineering,furthermore it plays an important role not only in tunnel durability,vehicle safety and comfortable level but also in economic benefit and social benefit,and it is also a key point in constructing tunnel.In the paper,the mechanics performance of semi rigid pavement,rigid pavement and continuously reinforced concrete pavement are analyzed by using the software of finite element analysis method(ABAQUS) for the pavement structure of Laoshan tunnel in Ninghuai highway,respectively concerning the effect of the intenerated roadbed,the separated roadbed and the sunk roadbed.Furthermore the initial cost of different pavement structure is also analyzed in detail.The reasonable structure formation of Laoshan tunnel is proposed based on the above analysis results.
