| 摘 要： | 地下通道开挖不可避免会对城市道路路面造成不良影响,其主要原因是由于地下通道在建设过程中产生了不均匀沉降而引起路面结构较大的附加应力.采用有限元法分析地下通道开挖的不均匀沉降量、不均匀沉降和路面自身结构参数对路面结构水平附加应力的影响,得出水平附加应力随各影响参数的变化规律,并提出了控制沉降量从而减小对沥青路面不良影响的措施.

| Abstract: | It is inevitable that the urban roads are often affected badly in the subway tunnel excavation.The main reason is that the non-homogeneous settlement which occurs during the subway tunnel construction often causes larger additional stresses in the road superficial structure.By using finite element method,this paper analyzes the influence of non-homogeneous settlement value,non-homogeneous settlement range and parameters of road superficial structure on horizontal additional stresses of road superficial stru... |
