高速公路桥梁桥面铺装层受力和破坏机理分析

Static behaviors and failure mechanism analysis on pavement layer on the girder of highway bridge

指出重载高速公路桥梁铺装层破坏是影响桥梁结构的一项主要原因,也是影响维修养护费用的主要来源之一,分析了桥面铺装的受力特点和主要受力分析模式,总结了几种常见桥面铺装病害,提出了设计控制因素和指标,为高速公路桥梁桥面养护提供指导。

The failure on pavement of heavy loaded highway bridge is a main reason which affect the health status of bridge. The most percentage of maintenance cost is come from the pavement repairing. In this paper, the main feature of static behaviors of bridge pavement and several force analysis mode are investigated, and the diseases of pavement are also discussed, the control design factors of bridge pavement is proposed, in or- der to give a guidance on the highway bridge pavement maintenance.
