永泰嵩口大桥状态检测评估

The detection and evaluation of the Songkou Bridge condition in Yongtai

根据永泰嵩口大桥桥型特点,采用静动载荷载试验、裂缝观测及承载力检算等技术手段对其承载能力和主要病害产生原因进行了分析评估,研究结果表明,嵩口大桥承载能力满足公路Ⅱ级设计荷载的要求,但大量超限裂缝的存在会影响桥梁的安全使用和耐久性能。

According to the characteristics of Songkou Bridge,carrying capacity and major disease of bridge were evaluated by using static and dynamic load test,crack observation means and computation of bearing capacity. The results show that carrying capacity of Songkou bridge meet the requirement of classⅡ highway design load. However,the safety and durability of the bridge were affected by the presence of a large number of overrun cracks.
