钢纤维喷射混凝土在隧道初期支护中的应用实践

介绍了钢纤维喷射混凝土在隧道开挖初期支护中的应用 ,并从其性能上与普通喷射混凝土进行比较 ,总结了钢纤维喷射混凝土的优点 。

This paper introduces the application of projected concrete strengthened with steel fiber to primary tunnel excavation and support. The performance of the projected concrete is compared with that of the common projected concrete and its advantages are summarized, so a new way is provided for construction of tunnels in weak surrounding rock areas.
