摘　　要：泊松曲线模型是一种增长型曲线模型。本文以某高速公路工程实例为例,根据三段法,利用La-grange插值法生成等时距数据序列求出最终沉降量后,将泊松曲线方程转化为线性方程,通过线性相关系数求出另外两个参数,建立模型。对比三点、六点、九点法可知,模拟曲线精度与所用点数的多少有关,点数越多越接近实测曲线。Poisson curve model is a growth to the three paragraphs, the use of Lagrange curve model. Taking a project as an example, according interpolation method to generate equal interval data sequence obtained after the final settlement. Poisson curve equations are translated into linear equations, and the other two parameters are extracted, by linear phase relationship, model is builded. Comparison of three point, six point, nine point method, simulation curve precision related to the points. The more points, the closer to the actual measured curve.
