城市建筑工程钻探噪声污染抑制方法研究

Methods of Controlling Noise Pollution from Drilling in Urban Construction Engineering

采用目前方法对钻探噪声污染进行抑制时,无法准确实现钻探噪声的预测,影响了钻探噪声污染抑制的效果。提出城市建筑工程钻探噪声污染抑制方法,采用抛物方程对钻探噪声的传播特性进行分析,并构建了钻探噪声传播模型和叠加模型。构建灰色系统预测模型分析钻探噪声与距离衰减之间的关系,通过欧拉算法对灰色系统预测模型进行求解,获得钻探噪声的预测结果。根据预测结果通过声屏障设计、噪声源密闭设计在城市建筑工程中完成钻探噪声污染的抑制。实验结果表明,所提方法的噪声偏差小,噪声污染抑制效果好。

The current method for suppressing drilling noise pollution could not the predict drilling noise accurately, which affects the effect of suppressing drilling noise pollution. A method for suppressing noise pollution from drilling in urban construction engineering is proposed. The parabolic equation is used to analyze the propagation characteristics of drilling noise, and a drilling noise propagation model and superimposed model are constructed. The gray system prediction model is constructed to analyze the relationship between drilling noise and distance attenuation, and the gray system prediction model is solved by Euler algorithm to obtain the prediction results of drilling noise. According to the prediction results, the noise pollution from drilling can be suppressed in urban construction projects through the design of sound barriers and the closed design of noise sources. The experimental results show that the noise deviation of the proposed method is small and the noise pollution suppression effect is good.
