引入各向异性的规则张力样条函数插值

Interpolation of integrated anisotropy into regularized spline with tension

为解决垃圾填埋场由于沉降引发的安全问题,需要进行沉降变形监测。本文引入变异函数的理论模型,对规则张力样条函数法的各向异性做适当修正,以解决沉降数据空间插值的空间变异性问题,并利用改进后的规则张力样条函数法,实现填埋场沉降数据的插值估计。试验结果表明,该方法能在一定程度上提高规则张力样条函数法的插值结果精度。

In the paper, a theoritical semivarigram function was introduced to modify the anisotropy of regularized spline with tension, so as to address the issue of the spatial variability of settlement data spatial interpolation. This modified method was applied for data sets from the settlement of a landfill. The resuhs showed that the interpolation accuracy of an integrated anisotropy into regularized spline with tension could be improved to some extent.
