试论道路桥梁施工中产生裂缝的原因及应对措施

On the causes of cracks in the road and bridge construction and the countermeasures

简要介绍道路桥梁施工裂缝的危害,从温度变化、地基沉降收缩、施工工艺、荷载变化等方面入手,探讨道路桥梁施工中裂缝产生原因,进而从温度控制、材料管理、施工控制和荷载设计四个方面提出道路桥梁施工中混凝土裂缝的防治措施,以加强道路桥梁施工质量控制。

Briefly introduces the harm of construction cracks of roads and bridges,starting with the change of temperature,the settlement of these four aspects of shrinkage,construction technology,load changes,to explore the causes of cracks in the road and bridge construction,and then from the cracks in the concrete road and bridge construction in the prevention and control measures of temperature control,the four aspects of materials management,construction control and load the design is proposed,in order to strengthen the quality control in the construction of roads and bridges.
