Numerous jet fuel monitoring facilities for buried double wall pipe systems dating from the late 1980 ’ s to the present 从80年代末到现在,我们给无数的军用机场燃料监控系统埋设双重地下管网系统。
It is very difficult to manage urban underground network ( including the sewage pipe network ) by handwork method 在我国绝大多数城市仍采用手工管理的方法来管理城市地下管网(包括污水管网) ,其弊端显而易见。
Lifelines include water , gas , heat transmission systems , communication networks , electrical power systems , sewer systems and so on 城市的供水、供气、热力、通讯、电力、排污等地下管网系统是现代城市生存和发展的生命线工程。
In the end , this paper discussed the technology of realizing webgis and characters of it , and predicted the prospect of application of this technology to the system of underground pipelines 最后,本文讨论了web - gis的实现技术及其特点,并对其在地下管网系统中的应用前景作了展望。

Most of lifeline network systems in chinese cities have not been passed through normal aseismic design , but many big and medium cities may be have the seismic risk background 我国城市的地下管网系统,大多数没有经过正规的抗震设计,而不少大、中城市又有着可能遭受中强地震影响的背景。
