爆破振动速度预测误差的可靠性分析

摘要

Error analysis of two kinds of blasting vibration velocity formula shows that both which have small relative errors, while the volatility is great. In order to avoid big errors volatility between the predicted values and the actual value and lead to unreasonable blasting design, the possibility of vibration velocity of the maximum error under certain reliability indexes by using the error analysis of reliability was put forward, which provided basis for evaluating blasting vibration.%通过对2种爆破振动速度公式的误差分析,发现虽然其相对误差均值都较小,但却都具有较大的波动性.为了避免由于误差的波动而导致预测值与真值产生较大性差异,而导致爆破安全设计的不合理,通过误差的可靠性分析,给出了在一定可靠性指标下可能产生的振动速度误差最大值,并可以根据不同构筑物的重要性选择合适的可靠性指标对预测值加以修正,为保证振动区域重要构筑物的安全提供了重要依据.
