| Abstract: | The mechanical properties and characteristics of steel fiber concrete and other concretes were compared and analyzed, and the technology theory of steel fiber concrete was discussed. Based on project practise the key construction technologies were introduced. The results show that supporting tunnel surrounding rock by steel fiber reinforced shotcrete can improve the structural parameters, mechanical property, waterproof property,durability and anti-corrosion property, which satisfies the requirement of ne... |
