摘　　要：使用VC6.0开发了土体人工边坡稳定性有限元直接评价与辅助设计系统,通过可视化对话方式实现了边坡的开挖、支护等工程的计算机设计。采用基于土体抗剪强度参数折减的有限元法直接评价边坡的稳定性,在迭代计算方案中使用了自适应弧长控制法。通过对多个人工边坡工程的稳定性评价,验证了系统的实用性。A system of direct evaluation and aid design for artifical soil slopes stability is developed with VC++ 6.0. In the system,finite element method is used to evaluate the stability of slope. Decreasing the strength parameters,c and j,of soil in steps,the safety coefficient can be directly calculated in an iterative process using self-adaptation arc length control technique. The presented method can be used to visually simulate engineering design,such as digging,retaining wall,anchoring,by interactive computation. The system has been used to evaluate the stability of many slopes in China with satisfying results.
