摘要
该文针对高速公路预应力混凝土连续箱梁桥的病害,采用现场调研与技术资料调查相结合的方法进行了详细地调查研究。重点调研了桥体开裂和破损等病害,根据病害出现的频率和程度对其进行了分级。调查结果表明:竖向裂缝、纵向裂缝、斜向裂缝数量占比较大;腹板斜向、竖向裂缝以及顶板纵向裂缝应予以重点关注。统计的高速公路桥梁中裂缝病害比较普遍,但是其病害程度总体可控。
A detailed investigation is carried out to the diseases of continuous box girder bridge with prestressed concrete on highway by combining field investigation with technical data investigation.The cracking and damage of bridge body are investigated and classified according to the frequency and degree of occurrence of the disease.The investigation results show that vertical cracks,longitudinal cracks and oblique cracks account for a relatively large number;The oblique,vertical cracks of the web and longitudinal cracks of the top deck of box girder should be paid more attention.The crack disease in the highway bridge is quite common,but the degree of disease is controlled.
