干噴鋼纖維混凝土在水電站進(jìn)出水口開(kāi)挖支護(hù)中的運(yùn)用

摘要: 鋼纖維混凝土是一種復(fù)合型增強(qiáng)混凝土, 它既有普通混凝土的特性, 又改善了混凝土的一些力學(xué)性能. 在桐柏抽水蓄能電站上水庫(kù)進(jìn)出水口邊坡支護(hù)的施工中, 通過(guò)優(yōu)選原材料、優(yōu)化混凝土配合比并加強(qiáng)施工質(zhì)量控制等, 顯著提高了混凝土的抗?jié)B性、抗裂性、延性、韌性及抗沖擊能力, 節(jié)省了支護(hù)時(shí)間, 加快了施工速度, 節(jié)約了施工成本, 可應(yīng)用于
支護(hù)工作量少和較小的工程中.

關(guān)鍵詞: 鋼纖維; 噴射混凝土; 邊坡支護(hù)

Abstract :As a kind of reinforcing concrete , steel fibre concrete is of better mechanical quality superior to ordinary concrete . The application of sprayed steel fibre concrete inthe slope support construction of reservoir intake and outlet in Tongbai Hydropower Station shows
its advantages inimpermeability,crack resistence , impact resistence and ductility , given proper mix proportion and qualified materials .The service test deserves populzing due to lower cost and time - saving .
