兰新铁路第二双线戈壁土地基沉降预测方法

Research on comparison among prediction methods for Gobi desert foundation settlement along the second double-line along Lan-Xin railway

利用兰新铁路第二双线实测路基沉降数据,分析了双曲线法,星野法,Asaoka法对戈壁土地基沉降预测的适应性,研究了各方法对波动数据的敏感性,以及预测结果误差大小及预测起始时间点选取对预测效果的影响,由此确定相应的预测方法与预测时间。

The study adopts the measured data for the foundation settlement of the second double-line along Lan-Xin Railway,analyzes the adoptability of the double-curve method,the Hushino method,and Asaoka method on the Gobi desert foundation settlement prediction,researches the sensibilities of these methods on the fluctuation data,and the influence of the errors from the prediction and the selection for the starting and ending time points in the measurement on the prediction effect,so as to identify the respective prediction methods and the prediction time.
