| Abstract: | Based on one piled beam-slab wharf project on the lower reaches of the Yangtze River, the cause for early-stage fissures on the super beam of piled beam-slab wharf and its expansion factor are analyzed systematically. Besides, the main control measures are introduced in the aspects of structural design, construction material selection, concrete proportion optimization and maintenance condition control, which could prevent concrete structures from earlv-staze fissures. |
