摘要
用双曲线回归拟合法、指数曲线拟合法和星野法3种方法进行了路堤沉降与稳定观测数据的处理,通过对拟合结果的分析说明了三种方法的各自特点。结果表明,3种方法的短期沉降预测能力均较好,星野法模型较其它两个模型与实际最贴近,双曲线模型与星野法模型拟合效果相近,而指数曲线模型预测的最终沉降量较另外两个模型偏大。
Embankment settlement and stability observational data be processed by hyperbolic fit- ting method, exponential fitting method and hushino method. The characteristics of each method by fit- ting results is analysis and described. Results show that the predictive ability of the short-term settlement of the three methods are better. The Hoshino method method most close with the actual observational data compared to the other two models. Hyperbolic fitting method with similar the hushino method. But Final predicted settlement by exponential fitting method is too large than the other two methods.
