湿喷钢纤维混凝土在拉西瓦水电站

喷钢纤维混凝土是在普通混凝土中掺入适量的钢纤维．依靠压缩空气将钢纤维混凝土高速连续地喷射到岩而，钢纤维混凝土与围岩密贴为整体，使围岩成为隧洞承载结构的主体。在地下工程中，可代替挂钢筋网喷混凝土支护。介绍了湿喷钢纤维混凝土在拉西瓦水电站地下工程巾的应用，以及湿喷钢纤维混凝土的特性、配合比设计、施工工艺等。

Application of Wet Jetting Steel Fiber Concrete to Underground Works in Laxiwa Hydropower Station

The jetting steel fiber concrete is made by adding suitable steel fiber to concrete, and jetting it to the surface of rock by compressed air with high speed continuously, to make it hang together with the rock body, which will bearing the tunnel stress and instead of other types of concrete. The application of wet jetting steel fiber concrete in the underground works of Laxiwa Hydropower Station was expounded, concerning the characteristics of SFC, design ratio of steel fiber to concrete, construction techniques and so on.
