A Discussion on Improving the Performance of Erosion and Abrasion Resistant of Hydraulic Building

This paper discusses the mechanism of sediment flow damaging hydraulic concrete,and analyzes the performance of erosion and abrasion resistant of hydraulic outlet building even the relationships between them with their body design,material selection,construction technology,operation and management.This paper also pointes out that determining the design parameters in the HF concrete on the basis of an experimental study and the spray polyurea elastomer abrasion resistant technology are effective ways to improve the the performance of erosion and abrasion resistant of hydraulic buildings.
