Abstract

Abstract

Based on the blasting excavation for the berm at the elevation of 640 m on the high slope of Xiluodu hydropower station, the blasting induced damage zone were obtained through sonic wave test and numerical simulation. The relationship between PPV and damage scalarD was studied. If PPV is bigger than one certain value, the damage scalar D increased quickly to about 0.8, then the increased speed became slow. A method of determining critical damage PPV was put forward based on the damage degree and it was compared with the methods of statistics relationship between the maximum tensile stress and PPV and the PPV criterion based on the maximum tensile stress. Results demonstrate that the accuracy of methods based on the damage degree and statistic relationship between the maximum tensile stress and PPV is better than the result according to the maximum tensile stress.
