Abstract：By integrating practical engineering examples,summarizing and further investigating the rockfill concrete dam construction technology are crucial for the enhancement and widespread adoption of this technique.The study focused on the dam construction material selection for the Zhaojiaba Reservoir's river-blocking gravity dam in Sinan County,Guizhou Province.It analyzed and demonstrated the advantages and disadvantages of C15 fine aggregate concrete block stone and C15 self-compacting rockfill concrete as dam construction materials from aspects such as material properties,construction processes,quality control,application effects,and project investment.The results showed that,given the same dam profile and volume of filling,the investment differences between the two materials were minimal.However,C15 self-compacting rockfill concrete exhibited stable performance,high safety factor,simple construction process,high degree of mechanization,fast construction speed,and easy quality control,making it significantly advantageous.The project selected C15 self-compacting rockfill concrete as the dam construction material.The advanced application of rockfill concrete dam construction technology in the Zhaojiaba Reservoir project aims to provide valuable reference for similar projects.
