摘　　要：针对大型岩体工程进行数值模拟时经常会带来模拟结果区域性误差较大的问题,通过分析发现不同区域的岩体性质、组织结构以及结构面的发育情况是造成模拟结果失真的重要原因。依据距离幂次反比法估值解决复杂地形地貌的建模问题,并根据岩体质量的好坏和表现在稳定性上的差异将大模型划分为若干个小区域,采用对每个特征区域分别赋予强度折减系数的办法来解决数值模拟结果失真的问题,取得了较为可靠的模拟结果。Aiming at the large regional error of large- scale rock engineering numerical simulation results,analysis is made,showing the key reasons for the error of simulation results are rock properties, geological structures and development of fault development of different regions. This paper attempts to use distance power inverse ratio method to solve the modeling of complex terrain,which divides the big model into small ones according to rock mass quality and stability difference,and gives strength reduction factors for each characteristic regional to solve the errors of simulation results. Reliable simulation results have been obtained.
