利用CAD技术对岩心复位的研究

Research of Core Restoration Utilizing the Technique of CAD

目前获取定向岩心结构面空间状态参数的方法主要有复位实测法、作图求解法和公式计算法。这 3种方法在利用测斜数据时 ,存在一些不可避免的误差。采用AutoCAD二次开发工具VisualLisp开发出岩心产状测试程序 ,利用计算机测量数据的精确性 ,直接测出岩心产状参数 ,提高精度。

The main ways to acquire the spatial state parameters of the texture plane of orientation core are the restoration measure, drawing solution and formula computation for the present. But the three ways all have certian inevitable errors, when using the incline data. The paper adopts has developed the program for measuring the parameters of core occurrence directly by means of the Auto CAD twice development tool-Visual Lisp by virtue of the precision of computer measuring data.
