Mesh generation method for three-dimensional concrete model

The invention provides a mesh generation method for a three-dimensional concrete model, which comprises the following steps of: performing mesh mapping on the three-dimensional concrete model to construct a three-dimensional concrete initial mesh model, judging the type of a mesh unit of the three-dimensional concrete initial mesh model to form a three-dimensional concrete mesh sample model, and performing mesh generation on the three-dimensional concrete mesh sample model according to a first preset difference value ratio, judging the accuracy of the three-dimensional concrete grid sample model, and outputting the three-dimensional concrete grid sample model with high accuracy as a three-dimensional concrete grid model; according to the method, the mesh generation process of the three-dimensional concrete model is simplified, the calculation complexity and the calculation amount are reduced, the consistency, the accuracy and the working efficiency of mesh generation are improved, local generation errors duri
