摘要
结合大秦线重载高速桥梁出现的裂缝现象,从荷载、温度变化、收缩、地基变形、钢筋锈蚀、冻胀、施工材料质量、施工工艺质量等方面分析了裂缝的产生原因,以方便设计、施工找出整治裂缝的合理措施,从而达到消除桥梁病害的目的。
Combined with the crack phenomenon of Da-Qin line heavy high speed bridge, the generating reasons of crack were analyzed from loading, temperature change, shrinkage, foundation deforming, concrete iron rust eaten, frost heaving, construction material quality and constmction technology quality so as to convenience design and construction and found proper treating measures, therefore erasure bridge diseases.
