Dongbo Zhao

Abstract

The application of the high-performance shotcrete construction technology in Wushaoling extra-long tunnel is presented,specific measures are proposed for the application of the high-performance shotcrete based on the disadvantages of the common shotcrete,the improve of the strengths,slump losses and rebound ratios of the shotcrete with active additives is described,the main features of the high-performance shotcrete construction technology are expounded and a good attempt in project cost management is made in the paper.
