导水断裂带发育高度的数值模拟
Numerical modeling about developing high of water flowing fractured zone
【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.
