【摘要】 对南宁市阳光新城地基开挖工程的爆破震动测试系统进行了介绍。对测试数据,运用数学回归分析法得到了具有科学性的精度可以被接受的K、α值,为预测震速提供了依据;运用灰关联分析法得出了影响爆破震动因素的主次性,依据主次性制定了合理的减震措施。采取减震措施后的测试数据证明了K、α值的精度可以被接受和减震措施的合理性。更多还原

【Abstract】 This paper introduces the blasting vibration test system of groundwork excavation project of sunshine new town in Nanning city.For the test data,the authors use a mathematics regressive analytic method to obtain the values of K and α.The scientific values of K and α and their precision could be accepted to offer a basis for forecasting the vibration speed;The grey correlation analysis is used to obtain the primary and secondary characters of factors that affect blasting vibration,and the rational shock absorption measures based on the primary and secondary character are taken.The test data after adopting vibration absorption measures prove that the precision of K and α could be accepted and the rationality of vibration absorption measure.更多还原
