摘要
Abstract
By using display dynamic finite element (LS-DYNA) method, the dynamic responses for constructing old dam and other main structures under blasting vibration load of the foundation pit excavation for constructing new dam is calculated for Fengman Hydropower Station. The vibration response control standards are determined according to rock plug blasting data in Fengman area and the experiences of other similar blasting engineering. The safety of old dam and other structures are assessed and a reasonable amount of blasting single fire dynamite is also determined. The calculation results show that the proposed largest single fire dynamite can meet the safety requirements of blasting, and the blasting vibration just has a small impact on the old dam and the sliding stability is guaranteed.关键词
