支持向量机驱动下的智能化工程地质分区探索
The Intelligent Engineering Geological Zoning Driven by Support Vector Machine(SVM)
摘要
Abstract
To address the challenges of traditional engineering geological zoning methods,such as difficulties in data acquisition,complex classification processes,and inefficiency,this study proposed an intelligent zoning approach based on Support Vector Machine(SVM)technology,and validated its accuracy through a case study of the Jijiawa gold deposit in Luoning County,Henan Province.This deposit exhibits complex engineering geological conditions,with dominant lithologies including biotite-plagioclase gneiss and hornblende-plagioclase gneiss,locally intruded by diabase dikes with poor engineering geological properties.The area was traversed by north-south trending faults,with unevenly distributed and well-developed joint fractures.Within a supervised learning framework,this study first constructed an engineering geological feature dataset.Based on known zoning data from exposed areas above the 700 m section,an SVM model was trained and subsequently applied to predict zoning in unexploited regions below the 700 m section.The research demonstrates that SVM,employing a Gaussian kernel function,effectively maps nonlinear geological features to a high-dimensional space,achieving linear separability of complex geological data.Under optimal parameters,the model achieved classification accuracies of 99.72%and 99.82%on the training and test sets,respectively,confirming its reliability and accuracy in complex geological conditions.The innovations of this study include:(1)establishing an SVM-based intelligent engineering geological zoning method;(2)validating its applicability under data-limited conditions;and(3)providing a scientific foundation for mining operations in complex geological environments.The results not only offer direct guidance for safe production at the Jijiawa gold deposit but also present a transferable technical solution for intelligent geological assessment in similar mining areas.关键词
