摘　　要：城市地下管线是城市赖以生存和发展的基础,如何有效指导实际开挖施工任务是当今城市地下管线管理一个亟待解决的问题。本文提出了一种城市地下三维管线开挖分析方法,通过管线段/管点与开挖面之间空间关系判别及管线段动态分段,实现任意开挖面下的地面开挖分析及相关数据统计,有效地解决了由于施工开挖面的任意性导致地面开挖分析困难的问题,为城市地下管线施工提供一个可行的指导方案。City underground pipeline is the basis for the survival and development of the city .How to effectively guide the actual excavation task is a problem to be solved in the management of city underground pipeline .This paper proposes a method for three‐dimensional excavation analysis of the city underground pipeline ,which can achieve analysis for any excavation surface and get the relative statistical data by judging the relationship between pipeline/ point and excavation space or dynamic segment .The method effectively solves the excavation analysis difficult problem ,which is caused by the arbitrary surface .This paper provides a practical guide for city underground pipeline construction .
