| 摘 要： | 在充分研究了水电工程现有勘测层数据以及径向基函数插值特点的基础上，利用径向基的分块插值方法建立起分块的三维地层模型。在每个分块插值过程中，利用加权函数，使得各个分块接边处保持连续性。在形成每一层的数据后，通过层数据之间的缝合，并加入断层信息，最后形成三维地层模型。基于小湾水电枢纽工程实例，采用径向基分块插值方法建立对应的模型，并提供任意剖面的获取，检验了网格分块地层体建模的正确性和可行性。

| Abstract: | Based on a comprehensive study of existing data of hydropower projects and the features of radial basis function(RBF) interpolation,a model for three-dimensional strata block via interpolation of RBF is built.During the process of blocked interpolation,a weight function in order to keep the continuity at the conjunction of two blocks is adopted.With the formation of the data for each layer,merging these data between layers and adding fault information,a three-dimensional strata model is obtained finally.Taking Xiaowan Hydropower Project for example,a corresponding model through the method of blocked interpolation of RBF is built;and access to any section is provided.Finally,the correctness and feasibility of grid blocked strata modelling are verified. |
