摘　　要：结合工程实例,采用ANSYS-2D,FLAC-2D和FLAC-3D程序对导水断裂带发育规律进行了大量计算和分析,认为:ANSYS-2D宜采用主应变指标来确定;FLAC-2D宜采用塑性区范围来确定;FLAC-3D宜采用应变增量(曲率)指标来确定.Based on project examples, many calculations and analysis for the development law of water flowing fracture zone were done by using ANSYS -2D, FLAC -2D and FLAC -3D which were present popular programs. It is considered that FLAC -2D and FLAC -3D are comparatively proper calculation programs. It is suitable using the simulation results of main strain for analysis in ANSYS - 2D and using the simulation results of plasticity zone in FLAC -2D and using the simulation results of strain increment in FLAC -3D.
