摘要
在目前评定桥梁或单梁的承载能力及工作状况静载试验方法的基础上 ,结合 3跨预应力双薄壁墩连续刚构和 5跨连续桥面简支斜梁桥的桥梁静载试验与分析 ,总结分析出常见桥梁的测试中 ,影响校验系数值的主要因素。建议在结构计算模式、材料实际强度取值及测量点布置方面再提高些要求 ,可大大提高校验系数 η值的精确度 。
This text is based on the present method to assess the loading ability and static load tests for working conditions of bridges or single beam. Through static load tests and analyses of a 3-span continuous prestressed concrete rigid-frame bridge with double thin-wall piers and a 5-span single skew bridge with continuous deck, main influence factors on coefficient of correction are concluded and analyzed in static load tests. Calculation mode, material strength and measure points are suggested to be more carefully considered according to actual construction and its behaviour, so that can increase the precision of coefficient of correction η . Thus, the assessment of loading ability and working conditions of bridges or single beam is more accurate.
