摘要
对ANSYS内置外角点外接圆摩尔匹配D-P准则,通过适当参数转换,可等效于M-C准则使用即可应用于岩质高边坡开挖的数值模拟。以水布垭溢洪道开挖边坡5-5剖面为例,通过子程序接口构建ANSYS、ADINA、FLAC3D网格模型,在同等条件下分别计算并对比了三类程序数值模拟结果的差异性和数值收敛、前后处理等难易程度。指出采用前两种软件计算的边坡相对位移均小于后者,ANSYS选用摩尔匹配的收敛性较差,对三维模型FLAC3D计算效率较高但前后处理功能较薄弱,这对岩土工程数值分析具有指导意义。
ANSYS only exterior exterior angle circumcircle point D-P model, the study shows that Moore matching D- P can match the M-C well. Through the appropriate conversion parameters, it can be equivalent to M-C criteria. In this paper, we chose the Shuibuya spillway section 5-5 as an example, established ANSYS, ADINA, FLAC3D model through the subroutine interface. Basing on the same conditions , three models were calculated and compared. Research results for the numerical analysis of geotechnical engineering have significance.
