摘要
杉树坪水电站引水隧洞采用了新奥法施工技术,作为新奥法的灵魂,现场适时利用锚喷、钢格栅等支护手段进行初期支护,有效地防止了围岩产生的有害松动变形,保持了围岩的完整性,保证了施工安全,并取得了良好的技术经济效益。
New Austrian method, with bolt-shotcrete and steel grid as its early stage supporting means, was applied in the construction of diversion tunnel of Shashuping hydropower station, which has prevented the loosening and deformation of surrounding rock effectively, kept the construction safely, and made a good technological and economic interest.
