To curtail the extra effect, and uses the measured sufficiently, slide multinomial fitting model is put forward.
多项式拟合是预测建筑物垂直沉降时应用最广泛的模型之一,但模型受外界影响较大。
The paper adopts the method of multinomial least squares as fitting to make the fitting function be simple and the amount of compensation interval be least, reduces the calculation cost.
同时,拟合方法采用目前非常成熟的多项式最小二乘拟合。从而不仅能控制拟合函数的复杂性,而且使分段拟合的补偿区间数量达到最少,极大地降低了计算成本。
