查询词典 pavements

When making design with bridge configuration, bridge deck overlay which was only treated as the appendant of bridge, currently not make special calculate and analyze about it, at the same time, current codes also just give directed account for method、material and thickness of deck pavements, there havent any design theory and index to dependent, so it is necessary to do some systemic study about concrete bridge deck overlay and make certain about the stress and distortion characteristic of the deck pavements.

桥面铺装作为特殊的路面结构，它起着保护桥梁和承担路面功能的作用。但是目前，在进行桥梁结构设计时，桥面铺装层只是作为桥梁工程的附属结构，一般不作专门的计算分析，现行规范也只是对桥面铺装的做法、材料、厚度做了指导性的说明，至今没有可以依据的设计理论和指标，因此有必要对桥面铺装展开系统的研究，明确铺装层结构的受力和变形特点。
