摘要
以趋势曲线预测模型中的多项式模型和指数模型为基础,基于熵权法建立组合预测模型,就其建模理论和计算流程进行系统分析,并对某滑坡体进行预测。结果表明,文中组合方法相对于其它组合方法而言,理论简单,能够有效地反映滑坡体的变化规律,且提高了拟合预测精度,在预测工作中具有一定的参考价值。
Based on the polynomial model and exponential model of the trend curve prediction model, a combination forecast model is built based on entropy weight method, of which the modeling theory and calculating process are analyzed so systematically that it can predict a landslide,The results show that the theory is simple, compared to other combination method, which can reflect the change rule of landslide effectively. In addition, it improves the fitting accuracy of the forecast,which can provide a certain reference value in forecasting work.
