摘要
通过简化爆破荷载的形式,对爆破振动作用下地基位移方程进行了推导,在此基础上给出了爆破作用下影响地基位移的诸要素,并提出了地基位移幅值在爆破作用下的变化规律,这对结构抗震工作的开展有着重要意义。
Displacement equation of foundation under blasting vibration action was deducted through simplifying blasting load.Base on this,factors affecting the foundation displacement under blasting action were pointed out and the variation law of the foundation displacement amplitude under blasting action was put forward,which is important significance for the development of structural antiseismic work.
