单板受力的成因分析及预防措施

Cause Analysis of Single Plate Loading and Prevention Measures

分析了预制板梁桥形成单板受力的原因，提出了增强桥面铺装混凝土厚度、加强铺装层内横向钢筋、加强梁板铰缝处凿毛、提高铰缝混凝土施工质量、增加铰缝钢筋等预防单板受力的措施。

The cause of single plate loading of prefabricated plate beam bridge is analyzed. Prevention measures such as increasing the thickness of bridge surface concrete pavement, strengthening transverse steel in pavement, strengthening joint treatment, enhancing concrete pouring quality and increasing joint steel etc. are put forward.
