一种优选组合法在软土路基沉降预测中的应用

在软土路基沉降预测中，常用的方法有简单曲线拟合法、系统分析和控制理论法等。但采用单一的方法进行预测，会造成预测误差偏大。提出了一种优选组合方法，通过对若干种单一方法进行权重化处理，给予每种单一方法相应权重，得出新的沉降预测曲线进行沉降分析，并以工程实例为基础，说明该方法在实际预测中是可行的。

Application of a Preferred Combination Method to Soft Soil Subgrade Settlement Prediction

In relation to soft soil subgrade settlement prediction, the commonly used methods are simple curve fitting, systematic analysis and control theory. However in the prediction, using single method may cause large error. Herein a preferred combination method was put forward, which takes several methods to be weighted, and gives each method a corresponded weight, then gets a new prediction curve for settlement analysis. Based on engineering example, this method has been proved to be feasible in practice.
