ABSTRACT = {Three-dimensional (3D) modelling of high-speed railways, bad 
geology, and special geotechnical engineering inferences may involve problems, 
such as inaccurate geological data, hidden underground geological phenomena, 
and complex geological processes. In this study, surface geological boundaries, 
drainage, transportation networks, covers, lenses, and small geological units are 
established using topographic surveying and mapping data, geological data, and 
geological exploration data acquisition. The 3D model of the karst system 
combines geological and mathematical interpolation curved surface 3D model 
simulation analysis, trend surface fitting, and interpolation of the NURBS surface 
and correct analysis. The model is used to describe the properties of objects,
including the geometry, topology, and attribute information. It can describe 
complex geological spatial information (geometric information and topological 
relationship) and the characteristics of various geological units and can satisfy 
the requirements for the expression and analysis of a complex geological body. 
Thus, 3D modelling is used as a reference for boundary representation and data 
in engineering geology.},
