桥面铺装一般分为沥青混凝土桥面铺装与水泥混凝土桥面铺装两种类型,设置于上部结构顶面,主要受到来自汽车荷载的作用。由于设计、施工与养护多方面的原因,桥面铺装往往会出现车辙和推移、裂缝类、松散、脱落以及泛油等病害,影响行车的舒适性与桥梁结构的安全性。本文分别就这些病害成原因进行了分析,并采用有限元分析的方法对桥面铺装的破损状态与修补状态进行了受力分析对比,桥面铺装在破损状态下应当及时选取材料进行修补,否则病害会很快加重。
Deck pavement is generally divided into two types of asphalt concrete pavement and cement concrete pavement, set in the top of the superstructure, mainly from the role of the car load. Due to many factors, such as design, construction and maintenance, decks and decks, cracks, looseness, falling off and oil panning often occur in the deck pavement, affecting traffic comfort and bridge structure safety. In this paper, the causes of these diseases are respectively analyzed, and the finite element analysis method is used to compare and analyze the damaged state and the repaired state of the bridge deck pavement. The bridge deck pavement should be repaired in time when the material is damaged , Otherwise the disease will quickly aggravate.
