| Abstract: | By studying on longitudinal crack along the pre-stressed wire at the bottom plate of box beam, it is important for construction to analyze the status of transverse secondary tension stress next to pre-stressed wire and possible construction deviation, with proposing the corresponding formula which calculates the thickness of protecting course of circle corrugated pipe. |
| Keywords: | continuous rigid frame bridges pre-stressed wire longitudinal crack |
