| Abstract: | This paper analyzes on the causes ofthe cracks on the prestressed concrete T -beam occurring in the winter construction ofthe Jingda Superhighway Engineering,points outthat the cracks can be avoided through m odifying partial reinforcem entdesign,changing the extracting pipe as the corrugated pipe,and strengthening the norm alized construction of each process,and probes into the treating m ethods for the prestressed T -beam having cracks on it. |
