摘要
文章以高速铁路某一观测点的路基沉降监测数据为实例,分别利用双曲线法、三点法、指数曲线法、Asaoka法进行了沉降预测分析,结果表明这4种预测方法的预测精度和相关系数较高,成果精度能较好的满足规范要求。
In this paper,the subgrade settlement monitoring data of a certain observation point of high speed railway is taken as an example,the settlement prediction analysis is carried out by using hyperbola method,three-point method,exponential curve method and Asaoka method respectively.The results show that the prediction accuracy and correlation coefficient of four prediction methods are high,and the accuracy of results can meet the requirements of specification.
