混凝土在桥涵结构物施工中的裂缝分析与控制

Crack analysis and control of concrete in the bridges and culverts structure construction

结合混凝土施工的现场观察资料,从温度应力、原材料质量、地基沉降、模板支撑、混凝土振捣及养护等方面分析了混凝土裂缝的原因,提出了相应的裂缝预防处理措施,使混凝土裂缝得到控制,从而提高结构物施工质量。

Combined with field observation data of concrete construction, the concrete crack reasons were analyzed from temperature stress, raw material quality, foundation deposition, template supporting, concrete vibrating and maintenance, Some prevention countermeasures were proposed so as to control concrete crack and enhance the structure construction quality.
