三维地质建模过程中综合地质剖面构建方法研究

综合地质剖面是三维地质建模重要的数据源,在地质构造复杂地区运用综合地质剖面构建三维地质模型的方法应用较为广泛。本文以成都市为例,详细介绍了综合地质剖面构建需要准备的地质资料、剖面的部署原则和构建方法,并解决了剖面构建过程中遇到的同时代、同层位的不同地层之间的连接问题。实践表明,通过综合地质剖面的构建,可以充分发挥地质技术人员在三维地质建模中的主观能动性,准确刻画复杂地质体在三维空间的展布情况,有效实现复杂地质体交互式半自动建模,提高三维地质建模的效率和精准度。

A geological 3D modeling method of comprehensive geological section for Chengdu

Comprehensive geological section is an important source of data for geological 3D modeling. Building geological 3D model by using comprehensive geological section is widely used in areas with complex geological settings. Taking Chengdu as an example, this paper introduces in detail the geological data to be collected for the construction of comprehensive geological profile, the deployment principle and construction method of the profile, and solving the problem of connection between different strata of the same age and horizon in the process of profile construction. Practice shows that the construction of comprehensive geological section can give full play to the subjective initiative of geologists in geological 3D modeling, accurately depict the distribution of complex geological bodies in 3D space, and improve the efficiency and accuracy of geological 3D modeling.
