摘要
以赵固二矿风井应用C90高性能混凝土为背景,对冻结井筒深厚黏土层504m处进行现场温度实测及数值模拟,实测与数值模拟结果一致且均显示外层井壁不会受到冻害,采用高强高性能混凝土可以有效控制井壁厚度,降低工程造价。
On application of C90 high performance concrete in Zhaogu second mining air shaft as background,this paper monitored the concrete temperature at 504m underground in deep and thick clay layer of freezing well,moreover the numerical analysis is done to the temperature. The results show that numerical simulation results are in agreement with the measured results,and the frozen will not happen at outer wall,so using the high strength high performance concrete can effectively control the wall thickness and reduce project cost.
