摘要
简要介绍钻孔电视成像的设备组成和工作原理,并对其解译技术和结构面产状计算进行简要说明。该方法技术可以将地质分层精细化,对微地质构造进行识别并科学测量倾向倾角。将钻孔电视成像应用于武汉地铁岩溶勘察,观测了解岩体完整性,岩溶、裂隙发育情况,充填情况,测定地下水含水层位置并分析确定岩层产状等。此外,通过生成三维钻孔柱状图,真实、直观地再现钻孔内的地质情况。
The equipment composition and working principles of borehole TV imaging are introduced in this article and a brief description of its interpretation technology and structural surface production are briefly described.This method can be used to refine the geological stratification.The paper identifies the micro geological structure,measures the inclination and declination,etc.Taking the subway karst survey in Wuhan for example,the authors observes the rock integrity,the karst and fissure developmental state and their filling situation,determines the aquifer location,and analyzes the rock formation by borehole TV imaging.In addition,through a three-dimensional drilling histogram,the authors obtain a real and intuitive reproduction of the geological situation within the borehole.
