| 摘 要： | 利用ABAQUS有限元软件,按强度折减技术对一实际工程大型节理岩质边坡进行了稳定性分析.针对ABAQUS程序节理材料模型的定义过于简化,只能将岩体视为满布节理的材料,节理视为相互贯通且遍布于岩体中,而不能根据实际节理面间距或分布密度来定义节理的缺点,提出了将受节理面控制的岩体进行"砖块式"划分的方法以模拟实际的节理分布情况.实例的计算结果表明,采用ABAQUS程序的节理材料模型弱化了实际岩体的强度,得到的分析结果过于保守,而采用将岩体"砖块式"划分的分析方法更符合实际情况,计算的结果更为合理可靠.

| Abstract: | The finite element software ABAQUS was combined with strength reduction technique to analyze the stability of the large jointed rock slope of a practical engineering.Aiming at the definition of jointed material model is too simplified in ABAQUS,including that rock could only be regarded as ubiquitous-joint material,joints were regarded as interpenetration and spread all over rock,and joints could not be defined according to practical joint spacing or distribution density,"brick-style"method of division was ... |
