摘要:为解决盾构区间监控摄像头布置的问题，本文以某盾构区间视频监控摄像头的布置为例，基于专家调查法，充分利用专家的知识和经验，得出地铁盾构区间需要重点监控的区域; 利用层次分析法，将地铁盾构区间监控区域选择的定性问题转化为监控区域重要程度指数的数学问题，从而得出某地铁盾构区间视频监控摄像头需要布置的位置; 再通过采用访谈的方式，向专家、盾构区间施工工人了解摄像头监控区域需要监控的项目和内容，得出盾构区间监控区域视频监控摄像头的监控内容表。通过确定盾构区间监控区域和监控内容，解决视频监控摄像头装而不用的问题，使监控系统发挥其实时掌握现场施工动态，增强施工现场的安全管理，减少安全事故的发生的作用。

Abstract: This article discusses how to arrange the shield zone surveillance camera with the arrangement of video surveillance camera in a certain shield zone as an example. Based on the expert investigation method, and the full use of the expert knowledge and experience, the article concluds that the subway shield zone needs to focus on monitoring the region. Using analytical hierarchy process(AHP) method, this article transfers the subway shield zone monitoring area selection into mathematical problems of the monitoring region important index, so as to obtain location of video surveillance cameras in a subway shield zone. The author talks to experts and construction workers about content of the project of the camera monitoring area and obtains the monitoring content table. By determining monitoring area and monitoring content of the shield zone, the problem of installing the video surveillance cameras without using is solved. Thus, the monitoring system masters the field construction dynamics, enhances the safety management of the construction site and reduces safety accidents.
