基于现场实测的缓倾硬性结构面连通率统计

Statistics of gentle angle rigid structural plane persistence ratio

通过对缓倾角硬性结构面数据的分析、判别,现场实测结构面几何特征的各基本要素,如结构面坐标、结构面产状、结构面间距、结构面的连续性、结构面迹长等,运用三维空间投影图解,最终求解结构面连通率,取代以往现场用线连通率经验判断的传统模式。本方法已应用于水电工程施工过程,效果良好。

Through gentle angle rigid structural plane data analysis,judgment,measures each base element of structural plane geometry characteristic in site,such as structure plane coordinates,structural plane strike and dip,structural plane spacing,structural plane continuity,structural plane length,using three-dimensional space projection graphic solution,solves the structural plane persistence ratio finally,and substitutes the former traditional pattern which judges with the line persistence ratio by experience.This method which has already applied and be tested in the hydropower project construction process has obtained a good result.
