Abstract:

The dam of Huangjinping Hydropower Station is an earth dam with asphalt concrete core. To reasonably determine the mixing ratio of filling material and construction technology parameters for the dam construction, the field test was conducted. The main test contents include asphalt parameter check, concrete mixing ratio test, concrete temperature at outlet of mixing machine, concrete grouting temperature, concrete spreading and rolling parameters etc. According to the test results and referring to the national standard, the reasonable materials and construction parameters for the dam construction were determined, which laid a solid foundation for the smooth construction of the asphalt concrete core soil dam.

Key words: earth dam with asphalt concrete core, mixing ratio of concrete, rolling test, construction technique, Huangiinping Hydropower Station
