时钢筋混凝土桥柔性桥面铺装的早期病害及其原因进行了分析与研究,在总结当前国内桥面铺装结构分析主要方法的基础上,通过理论分析,提出了用有限元进行结构分析时,需要重点研究的几个问题,指出了今后主要的研究方向.

Reasons for Early Stage Disease on Asphalt Concrete Floor

The paper makes research on reasons for early stage disease on flexible floor of reinforced concrete bridge. On the basis of summarisation of methods for floor paving structure analysis curretly at home, and through theoretical analysis, the paper puts forward some problems which need emphatical study over structure analysis by fi- nite element, and indicates out principal direction of research in future.
