三维计算模型快速建模方法研究

Research on Fast Modeling Method of 3D Computing Model

针对地质体三维计算建模的问题,文章介绍了2种从AutoCAD图件导出的坐标数据,利用Matlab编程语言进行处理,直接得到模型文件的建模方法。方法1针对连续的地层,提出了一种简单快速的处理思路,并支持从二维剖面图直接生成该断面的三维数值模型;方法2具有更强的适用性,能处理不连续的复杂地层建模。2种方法所建立的数值模型,应用于FLAC3D数值分析软件,分别对某失稳边坡与某高填方工程进行数值模拟分析,结果表明二者均是可行的。这2种建模方法对于降低数值建模的工作量有着较大的促进作用。

To solve the problem of 3D computational modeling of geological bodies,this article introduces two kinds of method which derived coordinate data from AutoCAD drawings,which are processed by Matlab programming language to directly obtain the modeling method of the model file.Method 1 proposes a simple and fast processing method for continuous stratum,and supports the direct generation of a three-dimensional numerical model of the section from a two-dimensional section;Method 2 has stronger applicability and can handle modeling of discontinuous complex stratum structures.The numerical models established by the two methods are applied to FLAC3D numerical analysis software to perform numerical simulation analysis on an unstable slope and a high fill works.The results show that both are feasible.These two modeling methods can significantly reduce the workload of numerical modeling.
