冻结施工内层井壁混凝土温度径向及时间维度的影响研究

摘要

冻结法施工中内层井壁起到封水和分担地压的双重作用，井壁质量至关重要。通过对红庆梁煤矿内层井壁温度的监测，分析了径向位置及时间对内层井壁温度的影响。分析表明入模72 h 时混凝土浇筑体内各点温度与径向位置呈线性关系。%The inner shaft lining in freezing construction plays the roles of sealing water and sharing ground pressure,so the quality of shaft lining is important� Through monitoring the temperature of inner shaft lining in Hongqingliang Coal Mine,the impact of radial position and time on the temperature is analyzed�The analysis shows that there is linear relationship between the temperature of points in concrete casting body molding after 72 hours and the radial posiG tions.
