随着城市化进程的不断推进,城市功能的调整和城市建设发展迅速,新建、改建、扩建项目不断增加,作为城市基础设施重要组成部分的生命线管网系统越来越复杂。本文基于地下管线探测仪,对不同材质管线探测方法和精度指标进行研究,以地理信息软件为平台,建立了某小区的地上和地下管线三维可视化系统,为青海省城市地下管线探测技术的发展进行了有益的探索,为城市生命线管网风险分析提供科学依据。 With the continuous progress of urbanization, the adjustment of urban functions and the rapid development of urban construction have led to an increasing number of new construction, reconstruction and expansion projects. Lifeline pipe network systems, which are an important part of urban infrastructure, have become increasingly complex. In this paper, based on the underground pipeline detector, the detection methods and the accuracy index of the pipeline with different materials are researched. With the geographic information software as the platform, the 3D visualization system of the aboveground and underground pipeline in a district is established, which is the development of the underground pipeline detection technology in Qinghai Province A useful exploration, provide a scientific basis for the risk analysis of urban lifeline network.
