大跨高墩曲线连续刚构桥荷载试验

Load Test of Long- span Curved Continuous Frame Bridge with High Pier

与常规直线桥梁荷载试验不同,曲线连续刚构桥梁荷载试验有其独特的特点。结合某高速公路上一座大跨高墩曲线连续刚构桥的工程实例,介绍了荷载试验内容、试验方法和静、动载的理论计算,分析对比试验结果,并对该桥的结构性进行了评价,得出满足《大跨径混凝土桥梁试验方法》规定的结论。对同类曲线连续刚构桥梁荷载试验具有参考价值。

Compared with the load test of conventionalstraight-line bridges, that of curved continuous rigid framebridges has unique characteristics. Taking an engineering case of a long-span curved continuous rigid frame bridge with high pier on an expressway for example, several key points are introduced in this paper such as contents of the load test, inspection methods, theoretical calculation, and analysis comparison of test results . Then, the evaluation of structural behavior is conducted, which can meet Test Methods to Large-span Concrete Bridges. In a word, this paper is of great reference value for tests of similar bridges.
