多面函数法研究鲜水河地区现今地壳垂直运动

Reseach on the Verical Crustal Movememnt in Xianshuihe Area at Present Time with Multiguadric Function

  • 摘要: 本文采用美国Hardy教授提出的多面函数模型,并考虑地壳垂直形变速率面的复杂性、不规则性,以及获取速率面信息的水准点分布的不均匀性,选取正双曲函数作核函数,选取光滑因子δ=0,对鲜水河地区1965~1988年的多期水准复测资料进行了计算,获得了鲜水河地区现今地壳垂直形变速率面的预测结果,较好地反映了鲜水河走滑断裂的现今地壳垂直形变及应变积累的特征。

     

    Abstract: Being used the multiguadric function suggested by Hardy professor of U.S.A,in this paper,and being considered the complexity and the irregularity of the velocity surface of vertical crustal movement and the inhomogeneity of the distribution of the benchmarks that the information of velocity surface are obtained from,a hyperboloid is selected as a kernel function and a glossy coefficient δ is decided to be equal zero.The calculation are done for the leveling network from 1965 to 1988 repeated over several periods.The forecasted results of the velocity surface of the vertical crustal movement are got in Xianshuihe area nowdays.It shows fairly the feature of the vertical deformation of the crust and of the strain accumulation in Xianshuihe area in these days.
