摘要

在充分研究了水电工程现有数据的基础上，根据水电工程数据的分布特点，提出了基于网格分块的三维地质体建模方法。并根据地表数据和地质数据的不同，分别提出了基于等高线切割的地表数据分块算法以及基于钻孔数据分布特点的地质数据分块算法，进一步利用边界缝合方法解决了分块引起的裂缝问题。在建立好三维地质体模型的基础上，根据网格分块的特点针对性的提出了基于网格分块的快速开挖算法。并分析了网格分块建立的地质模型比传统的地质模型的优势。通过西南某水电枢纽工程实例，检验了网格分块地质体建模的正确性和可行性。

Abstract

With the comprehensive study of the existed data of hydropower engineering

and considering their distributed characteristics

a method of 3D geologic body modeling based on grid partition is proposed. Due to the difference of ground surface data and geologic data

two different partition algorithms are proposed accordingly

namely

contour partition based algorithm of ground surface data and partition algorithm of geologic data based on the distributed feature of drill data; and edge matching method is used to solve of fracture caused by partition. After establishing the model of 3D geologic body

considering the feature of grid partition

a quick excavation algorithm based on grid partition is presented; and the advantage of grid partition based geologic model over the traditional geologic model is also analyzed. Finally

to test the correctness and feasibility of grid partition based on geologic modeling

an empirical study of a hydropower project is conducted.
