摘要
根据旧桥承载力评定方法新体系,结合多座二、三、四类桥的承载力计算评定实例,对各种评定系数及承载力计算进行对比,指出新体系对二类桥承载能力评定具有不合理因素,主要因检算系数取值范围偏大所致,进而对检算系数取值进行探讨,并提出了改进建议。
According to the new strength evaluation instances of evaluating method of bearing strength to existing bridge, combined with bearing many second - class.third - class and fourth - class bridges, every kind of evaluation coefficient and bearing strength calculations are compared. The result indicates that with regard to second - class bridges the new systerm has unreasonable factor, mianly for checking coefficient ranging larger. And then further discussed the checking coefficient ,and proposed some improved suggestion.
