Abstract：Trough disease treatment project of a stone arch bridge, which located from Guanyin Mountain to Qinshiya of Bao-Cheng line, the authors introduced geophysical detection method on stone arch bridge disease treatment. The stone arch bridge by using ultrasonic wave method and the CT method detection. The ultrasonic method for this kind of stone structure in bridge detection can obtain very good results. Combined ultrasonic transmission wave and ultrasonic CT method, can better detect stone arch bridge internal disease area position and size, for the treatment of stone arch bridge program provides a strong technical support, but also for the treatment effect detection provides a powerful means.
