光爆锚喷是“新奥地利隧道工程法”在国内的俗称,是一种把设计与施工凝为一体的技术方法。它创立于50年代,60年代得到迅速发展和广泛应用。70年代我国在镜泊湖、渔子溪、回龙山、白山、太平哨、碧口水电站,冯家山、龙羊峡、洛河故县水库等水电地下工程曾采用了光爆锚喷。我院选择清远县高车电站引水隧洞做光爆锚喷试点。一、隧洞概况高车电站引水隧洞由两条隧洞组成,其中:短洞长163米,长洞长526米,两洞间以石拱渡槽相连。隧洞设计流量17.7米~3/秒,按无压明流洞设计,采用方圆型断面,断面尺寸为4.6×4.2米(宽×高)。洞线顺山麓走向,理深较浅,隧洞
Light burst anchor spray is “New Austrian Tunneling Law,” commonly known in the country, is a design and construction of the integration of technical methods. It was founded in the 50s, 60’s rapid development and widespread use. In the 1970s, the light-blast anchor spray was used in underground hydropower projects such as Jingpo Lake, Yuzizi River, Huilongshan, Baishan, Taiping Whistle, Bikou Hydropower Station, Fengjiashan, Longyangxia and Luohe Guxian Reservoir. Our hospital chose Qingyuan County high car station diversion tunnel to make a light burst anchor spray test. First, the tunnel profile High car station diversion tunnel consists of two tunnels, of which: short hole 163 meters long, long hole 526 meters long, two holes to stone arch aqueduct connected. The designed flow of the tunnel is 17.7m ~ 3 / s. It is designed as a non-pressure Mingliu tunnel and adopts the square section with the section size of 4.6 × 4.2m (W × H). Cave to the foot of the foothills, Li Shao shallow, the tunnel
