| Abstract: | 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. |
