Problems solved by technology

However, it is very difficult for Flac3D to build complex models. Because the operation interface of Flac3D software is relatively simple, many operation commands need to be written using the built-in voice FISH, which is difficult for a designer or researcher.
Even if you have mastered the use of FISH language, it is still a difficult problem to realize the establishment of complex geometry and the mesh division of the model in Flsc3D, or even impossible

Abstract

The invention discloses a Matlab-based model recognition method for importing from Midas to Flac3D. The method includes the following steps that a three-dimensional simulation model is established with Midas / GTS software, grid partition of the model is carried out through a grid partition module of the Midas / GTS software, free grids and mapping grids are generated through a tetrahedral grid generator and a hybrid grid generator, and coupling of grid nodes of different parts is achieved; different material attributes are given to different parts of the grids; conversion of model information text files of Midas is achieved with Matlab software; the text files are output as importable files, with the extensions of .Flac3d and .dat, of Flac, an external grid input interface is found in a file menu of Flac, the text files are imported into Flac according to the path, and all groups of grids are displayed. By means of the method, error-free connection between Midas software and Flac3D software can be achieved.

Description

technical field [0001] The invention relates to the field of simulation research of geotechnical engineering, in particular to a Matlab-based model recognition method imported from Midas into Flac3D. Background technique [0002] With my country's rapid economic development and infrastructure investment in recent years, geotechnical engineering involving complex geological environments emerges in an endless stream. With the continuous progress in the field of geotechnical engineering, foundation pit engineering, tunnel engineering, etc. have also shown a trend of deeper excavation depth, larger excavation area, and more complex construction. As early as the early 1990s, the deepest foundation pit in China was about At present, there are not a few foundation pits with a depth of 30-40m. The tunnel excavation method has also developed from a simple mining method to a variety of shallow buried and underground excavation methods. In this situation, geotechnical engineering has ...
