基于模型辨识的曲线拟合法预测软土路基沉降

结合漳诏高速公路的路堤工程实际，探讨基于模型识别的曲线拟合法预测软土路基沉降。提出通过对预测模型的适应性检验，根据最小均方差和最大关联度法自动选择模型的思想，通过计算验证了模型识别预测沉降的思路和可行性，以及指数法、双曲线法和Asaoka法预测路基沉降的有效性和合理性，满足工程施工需要，为公路工程施工提供有益的借鉴。

Based on model discerning of curve fitting methods to forecast the settlement of soft clay subgrade under highway embankment

Considering the practice of Zhang-zhao highway embankment,this paper analyzed the settlement of the soft ground under the highway embankment by adopting the Curve fitting methods which based on model discerning.Base on the exponential method,hyperbolic method,Asaoka method,the idea to select calculating model automatically in the light of least deviation and highest degree of association is raised.The result from calculation and analyzed shows the thinking and the method in the paper are suitable,and they c...
