The underground powerhouse of Hongping Pumped-storage Power Station belongs to super-large section cavern excavation. The jetting area of bolt-shotcrete support is large,and the construction has lots of difficulties. The main application method and process of the steel fiber concrete is introduced. Steel fiber reinforced shotcrete spray evenly along the concave surface and has a good bond between the rocks. The cavern stability is guaranteed,and the construction safe is ensured. The construction program is also increased,and good economic benefit is achieved.
