岩体结构识别的三角多项式函数模式图方法

STUDY ON METHOD OF TRIGONOMETRIC POLYNOMIAL FUNCTION MODEL GRAPH FOR IDENTIFICATION AND CLASSIFICATION OF ENGINEERING ROCK MASS STRUCTURES

通过构造工程岩体结构分类的三角多项式函数，基于实际工程的各种岩体结构的典型特征，建立数学模型，并利用其数学特征所展示的韵律进行岩体结构类型的划分和识别。应用这种方法对长江三峡工程坝基块状岩体及清江高坝洲层状坝基岩体典型岩体结构建立三角模式图，作为各种类型岩体结构的标准模式图。岩体结构识别的三角多项式函数模式图方法为工程岩体结构类型的定量划分提供了一种有效的方法。

A typical trigonometric polynimical function model graph is constructed for clas sification and identification engineering rock mass structures. The typical mode l graphs for identification of engineering rock mass structures at dam foundatio n are presented for study of Changjiang Three Gorges project and Qingjiang Gaob azhou Hydropower project. The method of trigonometric polonomial function model is of practical significance for quantitative classification of engineering rock mass structures.
