【摘要】 针对目前独墩单铰支座曲线梁桥出现的通病 ,就温度对其梁体的变位影响以及预应力等因素对其支座支反力的作用进行了实例剖析。在此基础上探讨此类桥梁的支承体系的病害整治对策 ,并通过加固实例的监测结果予以验证更多还原

【Abstract】 To counter the common failing now in curved girder bridge with. single peir and single hinge beating, the paper gives examples for analyzing the influence of temperature on the deflection of the girder body as well as the action of the factors such as prestressing etc. on the inverse force of the bearing. On this basis the paper approaches to the countermeasure for disease harness of the bearing system of this kind of bridges. And it tests and verifies by the monitoring result of the consolidation example.更多还原
