| Abstract: | The Guanyinsha Bridge on the north section of Beijing-Zhuhai Expressway is a prestressed concrete continuous rigid-frame bridge.This paper presents the identifying of concrete creep coefficients by strain gauges embedded in the neutral axis of the main girder,separating of creep and strain by superposition method in the stress monitoring of the Bridge and sound effect of the monitoring achieved therefrom. |

| Keywords: | continuous girder bridge stress monitoring strain creep coefficient |
