摘要
Abstract
Due to the complicated geological condition of Gelantan Hydropower Station,the construction material supply is short during its construction period,thus the mixture of the local blast-furnace slag with lime stone powder in a certain proportion is taken as a new type of mixture,and then a deep experimental study is made on replacing the new double-mixture with flyash.Finally,the mixing proportion of 50 ∶ 50 for both blast-furnace slag and lime stone powder in the new type of mixture is selected and then the problem of the shortage of flyash is solved.Furthermore,for the problems of the joint energy dissipation of flaring gate pier-stilling pool-bottom outlet overfall and the anti-uplift stability of stilling pool,the technology of wet gallery for stilling pool is put forward in combination with both the flood characteristics and the geological condition of this project,thus the costs of construction and operation for the project are lowered.Moreover,aiming at that the foundation grouting impacts the rapid construction of roller compacted concrete,the method of the grouting without cover at first and then the secondary grouting is adopted and then the problem of construction interference is solved at last.Through the relevant technical innovations and applications,the construction of Gelantan Hydropower Station Project is smoothly carried out.关键词
