| 摘 要： | 目前沉降预测方法很多，各有其自身的优点，但尚存在一定的局限性，为了尽可能地利用全部有用信息，利用“组合预测”思想，提出一种对多种常用预测模型进行熵权法计算权重的组合预测方法，从而可根据有限的沉降实测数据达到预测沉降目的，工程实例分析表明，基于熵权的组合预测模型能够充分挖掘各模型的有用信息，大大提高了预测精度，具有明显的优越性。

| Abstract: | There are a lot of settlement prediction methods with their own advantages and limitations. In order to utilize as much as more useful information, a new forecasting method combining many models based on entropy weight has been put forward, which can forecast the embankment settlement by using limited measured data. The analysis of an engineering example indicates that the new method has high precision and obvious advantages. |
