【提要】 在建立边坡稳定问题的分析模型时，要建立计算程序易于识别的边坡地层模型。现有边坡计算软件的地层建模方法有直线段地层建模法、折线地层建模法和区域地层建模法。前两种方法比较繁琐，可视化程度低。基于软件技术的发展，展望了边坡软件地层建模方法的发展趋势，提出采用钻孔柱状图自动建立地层分布模型的方法，能实现高效的建模功能，大大方便边坡稳定分析的地层建模。

Abstract:When building analysis model to calculate the slope stability,the stratum model should be liable to discriminate by the calculation software.The existed methods including the straight line stratum modeling,the breaking line modeling and region stratum modeling are introduced .The former two methods are complex and the visualizations of them are poor.The trend of development is presented.It is suggested that the auto stratum modeling method using the holedrilled histogram can realize the modeling expeditiously and facilitate the modeling to calculae the slope stability.
