摘要
大体积混凝土的温度监测与控制对于避免或减轻其温差裂缝具有至关重要的意义。文中以某桥梁承台大体积混凝土为例,进行了混凝土参数计算,并根据结果分析提出了通过温控实现减轻温差裂纹的混凝土选材与浇筑工艺,施工措施和检测方案,有效防止了混凝土结构裂缝的产生,保证了工程质量,为后续工程的顺利实施提供了可靠保障。
The temperature monitoring and control of massive concrete are of vital importance to avoid or reduce the cracks caused by differential temperature in the concrete.Taking the massive concrete of a bridge bearing for example,the parameter calculations of the concrete are made here,and based on the analysis results,the material selection and pouring process,the construction practices and the monitoring program for the concrete to control the temperature and reduce the temperature cracks are proposed,thus to effectively prevent the generation of cracks in concrete structures,ensure the quality of the project,and provide a reliable guarantee for the smooth implementation of follow-up projects.
