VCR法在湖北白莲河电站尾水闸门井开挖中的应用

Application of VCR Method in Excavation of Outlet Gate Shaft of a Power Station

在湖北白莲河抽水蓄能电站尾水闸门井开挖中,通过对前期的大量爆破情况分析,求得爆破漏斗体积随药包埋深而变化的曲线,并成功应用VCR法进行闸门井的导井施工。通过本工程对VCR法的应用,表明水工建筑中的竖井也可以采用VCR法施工并能取得较好的效果。

In the implimentation of excavating the outlet gate shaft of Hubei Bailianhe Power Station,the blasting was analyzed to obtain a curve of variation of blasting volume with depth of cartidge,and the VCR method was successfully applied to the implementation.
