摘　　要：为解决传统基坑边坡及开口线设计方式工作量大、效率低、步骤繁琐并且制图精度及准确性难以保证的问题,研究并提出了一种基于APM的马道参数化建模与基坑智能开挖的设计方法。该方法实现了三维马道线的智能参数化建模及修改,由三维马道线创建的临时TIN进一步与地形DEM进行求交分析计算实现基坑开口线的自动生成。利用智能马道及基坑开挖技术可以辅助工程设计人员完成复杂的基坑边坡设计及开挖工程量"一键式"计算。For solving the problems of huge workload, low efficiency, difficult mapping accuracy guarantee in the design of foundation pit slope and opening line by traditional way, a Associative Parametric Modeling （APM） based design method of bench line parametric modeling and foundation pit excavation is studied and presented. This method can intelligently complete the parametric modeling and modification of 3D bench lines, and then the intersection computation between temporary TIN generated by 3D bench lines and terrain DEM will automatically create the opening line of foundation fit. By using parametric bench modeling and foundation excavation technology, the designers can easily accomplish the slope design of foundation pit and realize ＂one-click＂ calculation of the quantity of excavation.
