基于Matlab平台实现二维复杂地质模型多边形网格建模及重力异常正演计算
Polygonal grid modeling of 2-D complex geological model and calculation of gravity anomaly on Matlab platform
摘要
Abstract
Calculation of gravity anomaly from known geological model is an important method to interpret ab-normal density of medium by using gravity data.Modeling of 3-D geological body is difficult and inconvenient, and many 3-D linear geological bodies can be processed conveniently and fast as 2-D geological bodies.This paper built polygonal grid model of 2-D geological bodies and compiled software on Matlab platform to realize the calculation of gravity anomaly from complex 2-D model.The structure of the model is simple and the soft-ware executes fast.A comparative test with widely used calculation program IGMAS and the software in this pa-per is carried out using a profile in North China.The results show that the gravity anomalies calculated by the two softwares are almost identical.关键词
