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

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.
