摘要
将超短钢纤维混凝土的准静态力学实验结果作为参数,运用到钢纤维混凝土管片的数值模拟中,通过对软塑状黏性土、饱和粉土地层条件下不同材料的支护结果进行对比,得出在该地层条件下采用钢纤维混凝土管片可以有效减少隧道变形。
The quasi-static mechanical tests was conducted for ultra-short steel fiber reinforced concrete, with results taken as parameters for numerical simulation of steel fiber reinforced concrete segments. Based on the comparison among the supporting method with different material under soft clay, saturated silt, it is concluded that steel fiber reinforced concrete adopted for such soft ground would display superior performance in reducing the tunnel deformation.
