摘　　要：依据第Ⅰ部分所提出的非连续子母块体理论模型,应用Visual C++语言开发了基于Windows的面向对象的非连续子母块体计算分析模块。通过斜面滑块、两块体相互作用、悬臂梁端部受力等算例验证了所提出的非连续子母块体理论模型及所开发的计算分析模块的可行性与有效性。将开发的计算分析模块应用于石拱桥受极限荷载发生破坏失稳的工程实例中,通过与其他算法的计算结果进行对比讨论,证明了非连续子母块体理论模型在处理材料破坏问题方面的优越性。Based on the discontinuous sub-block model brought forward in the first part of this paper,the object-oriented numerical simulation program is developed with the Visual C＋＋ program language.The feasibility,validity and precision of the numerical simulation program are proved through some classical validation examples.At last,the numerical simulation program is applied to the failure simulation of a masonry arch bridge.The advantages of discontinuous sub-block model to deal with the failure of material are proved by comparing with the simulation results from other methods and discussion.
