码头现浇混凝土面层裂纹控制方法与实践

Control methods and application of wharf surface cast-in-situ concrete cracks

码头现浇混凝土面层易产生裂纹。裂纹对码头面层的观感和使用寿命存在一定的影响。文中分析了面层混凝土裂纹的成因,探讨了对裂纹进行有效控制方法,并依托罗泾二期工程水工码头面层施工对裂纹实施了有效控制。

Cracks are likely initiate on cast- in- situ concrete surface layer. In port engineering crackes in wharf will not only influence the visual quality of project, but also weaken the durability of structures. This paper has analyzed the surface layer concrete crack origin. The active control methods to the crack are discussed. Based on wharf surface con struction of the second phase of Luojing project, an effective control on cracks is carried out.
