摘　　要：对高原地区混凝土楼板开裂机理进行分析,基于高原地区气压低、干燥、寒冷、气候复杂等特点,从原材料合理选择、混凝土配合比优化及混凝土保温保湿养护等方面提出混凝土楼板裂缝控制措施。通过采用由挤塑板、塑料薄膜、棉毡等组成的新型保温保湿养护系统,在高效保湿养护的同时达到良好保温效果,提高混凝土施工质量。This paper analyzes the cracking mechanism of concrete floor slabs in plateau areas.Based on the characteristics of low air pressure,dryness,cold,and complex climate in plateau areas,concrete floor crack control measures are proposed from the aspects of reasonable selection of materials,optimization of concrete mix proportion,and concrete insulation and moisture conservation.It adopts a new type of insulation and moisture conservation system composed of extruded board,plastic film,cotton felt,etc.,which achieves good insulation effect while highly moisturizing,and improves the quality of concrete construction.
