在采矿、水利、铁道等工程中,经常遇到开挖爆破对边坡稳定影响的问题,需要在边坡坡面不同高程测量地震波参数(主要是质点振动速度V和加速度a),得出它们的传播规律,用以确定控制标准、限制爆破规模,并根据实测资料进行动力稳定分析。现仅就如何选择振动速度和加速度沿边坡坡面不同高程传播规律的公式作探讨。
In mining, water conservancy, railways and other projects, the impact of excavation and blasting on the slope stability is often encountered. The seismic wave parameters (mainly the particle vibration velocity V and acceleration a) need to be measured at different elevation of the slope, Of the spread of the law to determine the control standards to limit the size of the blasting and power stability analysis based on measured data. Now only on how to choose the vibration velocity and acceleration along the slope slope different elevation propagation formula for discussion.
