颗珠山山体控制爆破技术方案

Technical Program of the Controlled Blasting for Kezhushan Hill

东海大桥跨越颗珠山岛,山体爆破技术方案必须保证大桥安全。文章介绍了颗珠山山体爆破的预裂爆破参数、爆破控制参数、减小振动与防止飞石的技术措施、安全分析与监测方案等,成功实施了山体控制爆破。

The Donghai Bridge sits astride Kezhushan Islands,so the technical program of blasting for hills must ensure the bridge security.This paper introduces the presplitting blasting parameter,controlled blasting parameter,the technical measures to reducing vibration and preventing slungshots,safety analysis and monitoring scheme for the blasting of Kezhushan Hill,and the hills are successfully exploded under strict control.
