摘要
FLAC is the excellent software for rock and soil mechanics numeric simulating,but it does not perform well in modeling,especially to complex geological model,so its application is limited to some extent.In this paper,the modeling commands in FLAC software were analyzed and a new simple modeling method for FLAC was proposed and corresponding computer-aided modeling code was developed.To transform original coordinates of complex boundaries,get the boundaries uniform distributed transversely,and define the coordinates of each sub-grid column by column,then a model with complex boundaries can be built and it is easy to assign the material parameters and geo-stress boundary conditions.Our method can contribute to the numeric simulation of FLAC.
