摘　　要：研究了工程地质钻探中钻进不同地层时所产生噪声及随距离衰减状况,建立了工程地质钻探噪声随距离衰减的灰色系统预测模型,并用改进欧拉算法进行求解.监测数据及预测结果表明,对不同的地层结构,工程地质钻探所产生的噪声有较大的不同,且随距离的衰减也不同.采用改进的欧拉算法求解灰色系统模型简单快捷,预测结果与实测值基本符合.The noise size and its attenuation with distance produced during drilling different layer in the engineering geology drilling was studied. The gray system prediction model GM（1,1） of the noise was established and solved using value solving technique （improved Euler method）. Monitoring data and predicting results showed that noise produced from engineering geology drilling on the different layers was different and also different with attenuation of distance. Using improved euler method to solve the grey system model was simple and rapid. The predicted value accorded basically with the surveying value.
