| 摘 要： | 建筑打桩施工的噪声和振动,由于在实际传播过程中的未知因素很多,难以建立较高精度的物理预测模型。该文利用灰色系统理论建立GM(1,1)预测模型,用现场实测数据构成原始序列,以原始数据进行累加生成,计算打桩施工噪声级和振动级按坐标分布的预测值,其结果与实测基本相符,预测精度达到一级。

| Abstract: | Physical prediction model is difficult to establish for noise and vibration in building construction due to unknown factors encountered in the actual propagation process.Using grey system theory,we set up a GM(1,1) prediction model,construct an original sequence by on site data,and calculate the theoretical values of noise and vibration grade along axle.The predication results obtained are in close agreement with the measurement data,with prediction precision achieving one grade. |
