摘要
Abstract
The concrete face rockfill dam of Puxiqiao Hydropower Project, 140m in height, is designed for a rock-earth filling volume of 384.5×10 4 m3 . It is mainly composed of quarry material from Gejieqing quarry site and ex-cavated material from construction of structures. After commencement of the construction the area geologically af-fected by the fault and the development extent of fissures in Gejieqing quarry site were found significantly in-creased as compared with those known in the design and planning stage. What’s more, rock strata intercalated clay widely spreads and the excavated material is mostly of soft rock(mudstone). The compaction parameters have been determined by compaction test in a scientifically sound way. The dam has been filled according to the compaction test parameters since March, 2012 and a rock- earth volume of 240×10 4 m3 has been filled so far. The field test has proved that the filling quality is satisfactory.关键词
