摘要
Abstract
The No. 2 spillway tunnel in Luding Hydropower Station is a tunnel with extra-large section. The excavation section is large and wide, and the geological condition is complex. The section of the tunnel passing through the Hunshui Ditch is especially shallow-buried with a smallest rock embedded depth of 6m. Based on the geological information and field survey, the surface and tunnel treatments are combined to deal with the problem. The treatments ensure the successful excavation and support, on schedule.关键词
