摘 要:城市地下管网综合图的质量隐患,作业人员俗称作业雷区。简单分为以下4类:第一类是地下管网综合图中地形要素制造的雷区。第二类是地下管网综合图中地下管线要素制造的雷区。第三类是地下管网综合图中人为"粗差"因素制造的雷区。第四类是地下管网综合图中自然因素制造的雷区。urban underground pipeline comprehensive map quality hidden trouble, homework personnel commonly known as homework mine field. Simple is divided into the following four types: the first kind is the underground pipe network integrated diagram terrain factors made mine field. The second is the underground pipe network integrated diagram of the underground pipeline elements made mine field. The third type is the underground pipe network in the composite chart as “gross error” factors made mine field. The fourth class is underground pipe network in the composite chart of natural factors made mine field.
