混凝土桥沥青铺装层力学计算分析

桥面铺装是桥面行车体系重要组成部分,由于桥面铺装的受力模式不同于一般的沥青路面,沿用原力学计算方法不能较准确地揭示桥面铺装的真实受力状态。文章将桥面系和沥青混凝土铺装层作为统一的力学计算体系,研究了桥面铺装体系的力学特性和分布变化规律,为桥面铺装层体系设计和选材提供理论依据,达到改善铺装层受力和延长铺装层使用寿命的目的。

Mechanical calculation and analysis of bridge deck pavement of the concrete bridge

Bridge deck pavement is an important part of vehicle system. Because the mechanical mode of bridge deck pavement is different from that of the usual asphalt pavement, the mechanical calculation method for the usual asphalt pavement can not reveal the actual mechanical state of bridge deck pavement. In the paper, the bridge deck system and bituminous concrete pavement are regarded as an integrate mechanical calculation system,the mechanical property and variational rules of the paving system are studied in order to provide a theoretic basis for the paving system design and to improve the stress distribution and service years of the pavement.
