| 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.

| Abstract: | 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. |

| Keywords: | water flowing fracture zone numerical simulation plasticity zone main strain strain increment |
