Abstract:
Associating with the west end expansion engineering of Changsha Juzizhou Bridge, Hunan Province, some key problems arising in the expansion project of multi-span double arch bridge expanded by continuous bridge were discussed. Analytical results show that the reasonable construction control can prevent the original multi-span arch bridge from cracking. The revising of construction measurement will benefit from the displacement monitoring data. The varying magnitude of the structural strain created by the varying temperature is greater than the expansion construction. During the field measuring by metal strain gauge or manual strain gauge, the interference affection of environment is great, and the measuring strain is greater than the structural strain by loads.
