【摘要】：薩道夫斯基公式主要應(yīng)用于大藥量爆破,在工程實(shí)踐中,該公式的參數(shù)k和a變化范圍較大,難以選取,通常認(rèn)為薩道夫斯基公式僅用于大藥量爆破且并未考慮高程對(duì)爆破振速的影響,很多學(xué)者提出了修正公式,基于這思路,通過(guò)現(xiàn)場(chǎng)小藥量實(shí)驗(yàn)對(duì)不同高程的爆破質(zhì)點(diǎn)振速進(jìn)行回歸分析,驗(yàn)證了薩道夫斯基公式適用于小藥量爆破并且考慮了高程效應(yīng)。在實(shí)際工程應(yīng)用中,應(yīng)當(dāng)先根據(jù)工程地質(zhì)情況確定相關(guān)系數(shù)值,再使用薩道夫斯基公式或者修正公式就會(huì)比較準(zhǔn)確。
[Abstract]:The Saadolski formula is mainly used in large explosive blasting. In engineering practice, the parameters k and a of the formula vary greatly, so it is difficult to select.It is generally believed that the Sadolski formula is only used for large explosive blasting and does not take into account the influence of height on the blasting vibration velocity. Many scholars have proposed a modified formula based on this idea.By regression analysis of the vibration velocity of blasting particles at different heights, it is proved that the Sadolski formula is suitable for small explosive blasting and the height effect is considered.In the practical engineering application, the correlation coefficient should be determined according to the engineering geological conditions first, and then it will be more accurate to use the Sadolski formula or the modified formula.
