摘要:受内外界环境的影响,作为地质体一部分的浅海相土体有其特殊的结构特征。为了从
整体上表达和再现浅海相土体结构,需对其三维模型的建立进行研究。提出了将克里金插值
方法与 GOCAD 建模软件相结合以及采用 GOCAD 中的 Surface 对象代替 Structural Modeling
功能创建面模型,再基于面模型建立三维地质模型的方法。以某工程为例,建立了该地区的
三维地质模型,通过对不同方法建立的实例模型的对比分析,指出该方法所建的模型精度较
高,能够比较真实地反映浅海相土体结构特征。

Abstract: With the influence of internal and external environment,as a part of the geological body,
shallow marine facies soil has its special structure characteristics. To express and reproduce the
structure characteristics of shallow marine facies soil entirely, the building processing of its 3D
model needs to be bining Kriging interpolation method with GOCAD
modeling software, using Surface object instead of Structural Modeling in GOCAD to create
surface model which the 3D geological model is created based on is put 3D
geological model of a project produced by the method has a higher accuracy than the models
created by other methods ,and can truly reflect the structural features of shallow marine facies soil.
