摘要
根据辽宁地区桥梁承载力下降检测资料,应用灰色系统理论对在役桥梁劣化趋势进行分析,提出以时间与状态得分为等间隔初始序列,推导出桥梁劣化预测模型按指数分布表达式,并对检测序列进行分析验证,为桥梁劣化预测提供参考。
According to the detection data of bridge bearing capacity decrease in Liaoning,the grey system theory is used to analyze the detection trend of bridges in service.Equidistant initial serial of time and status scores is put forward.The exponential Distribution expression of bridge deterioration prediction model is deduced.And the detection serial is then analyzed and validated to provide reference for bridge deterioration prediction.
