三维地层构造发展现状

 三维地层模型在地下空间开发、油气资源开发和岩土工程问题分析中具有重要作用。论文系统总结了国内外学者在三维地层构造方面的研究，从3个方面系统阐述了三维地层构造的研究现状：①几种常用三维地层的面模型和体模型的建模原理、数据结构和各自的优缺点；②三维地层层面、层体的构造方法以及对特殊地质的处理方法；③三维地层模型误差产生的原因及其修正问题。最后，指出了三维地层构造研究中存在的一些问题，并对其发展趋势进行了展望。

Development Status of 3D Stratum Construction

Research on 3D stratum model has an important significance on the development and utilization of underground space，development of oil and gas resources and the analysis of geotechnical engineering problems. This paper is systematically summarized the present research of the construction method of 3D stratum. It includes three parts: (1) data structure，modeling principle，advantages and disadvantages of several common 3D stratum surface models and solid models；(2) the 3D stratum layer and solid construction methods and the special geological processing methods；(3)error analysis in 3D stratum model and its correction method. Finally，some issues concerning about 3D stratum model is discussed and their developing trends are pointed out.
