摘要
以深圳地铁9号线西沿线项目为背景,通过对深孔孤石爆破震动监测数据回归分析,求得在深圳填海地质下的单段最大爆破药量,并提出相关减震和保护措施,以确保施工中震动峰值在规定的范围。
Taking the project along the west of Shenzhen Metro Line 9 as the background, through the regression analysis of the vibration monitoring data of deep-hole solitary blasting, the empirical formula of single-stage maximum explosive charge under the geological condition of Shenzhen reclamation is obtained, and the relevant shock absorption and protection measures are put forward to ensure that the peak value of vibration in construction is within the prescribed range.
