摘要
近坝区爆破施工产生的爆破振动将会对土石坝产生一定的影响。结合爆破理论与工程实际,通过Geo-Studio建立大坝有限元分析模型,分别从坝坡稳定、坝基液化等方面分析了爆破振动对大坝的影响效应,对爆破方案及施工期大坝安全监测、设施防护提出了合理的建议。
Vibration caused by blast construction at near dam region will affect the safety of earth-rock dam. Combined with blast theo- ry and practical projects, the finite element model of dam was formulated by Geo-Studio, The effect of blast vibration on earth-rock dam was analyzed from the aspects of slope stability, soil liquefaction in the foundation of earth-rock dam and so on, and some advices were proposed about monitoring the safety and the safety protection facilities durin~ constructinz earth-rock dam and blasting schemes.
