摘　　要：钢筋混凝土梁板因其构造简单、施工方便、造价较低而在中小跨经桥梁中大量采用。然而,由于设计、施工以及管理养护等方面原因致使部分梁板出现一系列破损和缺陷。针对钢筋混凝土桥主梁板存在的缺陷和病害,从设计、施工等角度简要分析了各种病害产生的原因和表现特征。同时针对不同病害提出了相应的修补技术措施。Reinforced concrete beam slabs are heavy used in bridges with mid and minor spans because of their simple texture, convenient construction and less cost. But a part of beam slabs yields a series of damages and defects owing to causes of design, construction, management and maintenance etc. The paper shortly analyzes the causes and the features of various disease from design, construction etc, and aiming at defects and diseases existing in beam slab it proposes appropriate remedying measures.
