摘要
通过介绍三维地质建模的意义以及应用GOCAD软件进行三维建模的原理和方法,以本溪地区深部地质调查为例,对本溪地区的地层、构造、岩体进行分析并建立三维模型.每个地质三维模型都能更好地反映地质体在三维空间的分布形态,同时也可以根据研究目标不同,建立所需的目标地质体的三维形态.深部地质三维模型的建立除了依靠地表信息外,还要靠钻孔、地球物理等先进的技术手段的约束来不断修正、完善模型,共同建立一个符合地质规律、能真正反映客观地质现象的三维模型,为以后地质技术人员认识地质现象提高效率.
By introducing the 3D geological modeling with principle and method of application of GOCAD software, taking deep geological survey in Benxi region for example, the authors analyze the stratum, structure and rock mass and establish3 D models. Each geological 3D model can reflect the distribution pattern of geological bodies in 3D space better, meanwhile the 3D shape of required target geological body can be established according to different research objects. Deep geology 3D modeling relies not only on surface information, but also the technical constraint of drilling and geophysical data to improve the model, which would conform to geological regularity and truly reflect geological phenomena, and could help geologists recognize geological occurrence and improve work efficiency in the future.
