| 1. | The attenuation indexes of vertical direction components and level radial components of blast earthquake wave in the condition of far range are all larger than the one in the condition of close range . based on upwards analysises , relevant control ways and safety defending technology of blast vibration are given from the aspects of blast equipments , blast parameters , landform physiognomy , blast methods . and taking the practical data from blast scene as the sample , the blast shockproofness are forecasted by the feedforward nerve network model based on the prior knowledge of blast shockproofness , the regress analysis method and experience formula method , which supply the technology gist for
并且,以爆破现场的实测数据为样本,采用基于爆破震动强度先验知识的前馈网络神经模型、回归分析法及经验公式法分别对爆破震动强度进行了预测研究,为爆破施工参数的确定提供了技术依据,确保整个爆破工程顺利安全进行,并对这三种方法的预测结果进行了对比分析;对比分析表明,三种预测方法计算出来的结果精度相差甚大,从检验样本值与预测结果值之间的相对误差可以看出,人工神经网络法预测的结果较其他方法更接近于实际值,回归分析预测法的精度又要高于经验公式预测法。 |
