The present application provides a method for constructing a three-dimensional numerical model of a deep anticline structure and stratigraphic structure, which is used to accurately construct a three-dimensional numerical model of an anticline structure, thereby creating an accurate and effective basis for subsequent finite element analysis. The method includes: obtaining initial data of the target anticline structure, wherein the initial data is collected by means of caving or drilling, and the initial data includes the axial geometric parameters, formation occurrence, formation composition and formation of the target anticline structure structure; based on the content of the initial data, build a 3D solid model of the target anticline structure, wherein the 3D solid model is used to restore the 3D solid structure of the target anticline structure; use the unstructured hexahedral mesh to divide the 3D solid model, The fault structure in it is meshed to form a three-dimensional numerical model for finite element calculation, wherein the three-dimensional numerical model is used for geomechanical analysis and numerical simulation analysis of the target anticline structure.
Description
technical field [0001] The present application relates to the field of geology, in particular to a method for constructing a three-dimensional numerical model of a deep anticline structure and stratigraphic structure. Background technique [0002] In complex deep geological structures, the formation of anticlines by tectonic stress compression is a very typical geological tectonic unit, and is the most frequently encountered structural form in deep engineering construction. [0003] The biggest impact of deep anticline structure on underground engineering construction is that it is the imprint of the history of tectonic movement. The rock mass structure in the region has become diversified due to the tectonic compression and deformation, and the stress field in the region has also become extremely complex. Due to the combined control of many factors such as stratum geometry and mechanical properties, the surrounding rock often exhibits extremely complex mechanical behaviors ...
