A STUDY ON THE BLASTING VIBRATION CONTROL OF CREEP MASS HIGH SLOPE

摘要：

The borehole blasting vibration of the creep mass high slope of a hydropower station is observed, analyzed and processed. The decay experience formula of the blasting earthquake wave is obtained, with which elevation effect is considered. Based on features of the creep mass high slope of the hydropower station, several damage standards for the borehole blasting vibration are given. On the basis of the decay experience formula and damage standards, the blasting safety control parameters of new cast-in-situ concrete of the creep mass high slope are derived. At last, in the light of construction characteristics of the creep mass high slope, the control measures of the blasting vibration are proposed. The construction effects of the project prove that the research achievements of this paper are applicable in the project, and the blasting of the project is satisfactorily finished.
