| 摘 要： | 在基体对面层现浇混凝土变形约束的条件下,温度、湿度变形引起的收缩应力是码头面层裂缝产生的主要原因。在码头面层中引入补偿收缩混凝土,减少基体对面层的约束,可以做到面层少出现或不出现裂缝。

| Abstract: | When the deformation ofcast-in-situ slab concrete is restrained bythe base, the shrinkage stress caused bytemperature and humiditychange is the main cause offace slab concrete crack. By applying compensating shrinkage concrete in wharf face slab, the restraint on slab concrete is reduced and the concrete crack can be cut down or eliminated. |
