人工填土高边坡爆破振动动力响应分析研究
|
摘要
通过现场测试,利用频谱分析方法,得到了生产爆破引起的地震波在人工填土高边坡中传播特性和基本规律的研究成果;利用有限元软件,结合实测数据采用模态叠加法,对研究边坡进行了动力响应分析,分析了该边坡表面的加速度及位移分布规律、边坡破坏的形式。
Based on the tests and measurements at a high fill slope site, this paper utilizes the ng frequency spectrum analysis method and examines the characters and basic regular about how the blasting waves transmit in slope. The dynamic response of the fill slope is further analyzed with the modal superposition of finite-element method. Based on the two analysis methods, the damaged mode, the acceleration and displacement regulars of the slope surface are characterized.
