摘　　要：本文介绍了爆破地震动强度的预测方法和该领域研究的国内外现状,以岭澳核电站场地为例,利用该场地土石方工程爆破时实监测获得的大量实验数据进行统计回归分析,提出了一种估计(折算)爆破药量的方法,给出预测爆破地震动加速度、速度、的经验公式。按此地震动衰减规律并结合时实监测数据指导爆破,确保大亚湾核电站的安全运行。这种折算爆破药量的方法和预测爆破地震动强度的经验公式对指导工程爆破具有重要参考价值。The recent developments in world of the forecasting intensity of ground motion induced by engineering explosion are introduced. Based on the statistical analaysis of measurement data obtained in monitoring the excavation blast operation at Lingao Nuclear Power Station, a equivalent explosive method is proposed, and the attenuation of ground motion induced by explosion are analyzed. The results can be used for controlling explosion works and ensuring the safe operation of Dayawan Nuclear Power Station. The method and experience formulas have referential valve for giving a direction of engineering explosion.
