摘要
依据某高速铁路实际沉降观测数据,采用双曲线法、指数法、浅岗法和三点法四种预测方法进行预测分析。结果表明,针对"小量级大波动"的沉降预测数据,浅岗法的预测效果优于其他三种方法。
On the basis of a high-speed railway actual settlement observation data,using the hyperbolic method,exponential method,Asaoka method and three point method of four kinds of prediction methods were predicted and analyzed.The results show that the prediction of settlement data of small scale fluctuations,Asaoka prediction is better than the other three methods.
