AutoCAD在隧洞地质展示图编制和空间分析中的应用

Application of AutoCA D in the Workout for the Geological Layout of Tunnels and Spatial Analysis

绘制隧洞地质展示图是施工过程中客观反映洞室围岩地质条件的有效方法 ,但由于其表示的信息较简单且采集不便 ,难以进行深入的空间地质信息分析。应用AutoCAD内嵌语言Autolisp ,编制出用于切制横剖面和高程平切面图的程序 ,供AutoCAD调用。在洞群区 ,分别在各洞室切制统一的横剖面图和某一高程的平切面图 ,构成洞群区三维空间地质信息系统的模型 ,为进一步的空间分析提供依据。

Protracting tunn el geological layout is deemed to be an efficient method to reflect the gologica l conditions of tunnel’s wall rocks obje ctively in the course of construction, b ut as the collection is inconvenient and the data it denotes is simple and incom plete, further analysis for spatial geol ogical information is difficult to be co nducted. Apply Autolisp, an in-lined lan guage of AutoCAD, may work out proceedin gs to dissect cross sections and horizon tal sections of the elevation and be all ocated by AutoCAD. In the area of group tunnels, unified cross sections and hori zontal sections of a certain elevation f or each tunnel will be dissected respect ively, so as to build a model of three d imensional geological data system and pr ovide basis for further spatial analysis .
