In traditional geological modeling methods

the expression of the stratigraphic model is inaccurate and the stratigraphic boundary has a sawtooth phenomenon. Moreover

due to the large amount of model data

it cannot be smoothly loaded and rendered on the Web side. To solve these problems

this paper proposes a three-dimensional (3D) geological modeling method based on regular voxel splitting. This method first uses the boreholes and geological section data in the geological survey for data conversion and fusion

and encrypts the stratum vector point through the interpolation algorithm

and then constructs and divides the regular voxels

and designs 5 different regular voxel splitting types. At the same time

the data structure design of the voxel splitting model is carried out

and the irregular voxel metadata structure is analyzed and displayed through Three.js. Using this method

a 3D geological model was constructed based on the survey data of a certain area of Zhengzhou City

and the Web-side visualization was performed. Experiments have proved that the constructed model can accurately and smoothly express different stratigraphic structures

and can realize rapid rendering
