概述地球物理勘探是以地下物质的物理特性差异为基础,利用物理学原理,通过观察和研究物理场(电磁场、磁场等)的空间与时间的分布规律,实现对地下目的体的勘探。说得通俗一点就是:利用物性差异,分析判断埋在地下的东西。城市供水管网大多敷设在地下,随着城市建设的发展,很多地形参照物发生了改变,时常难以从原图确定管位;同时,管线探测也是建立城市地下管网数据库和实现计算机动态管网管理的基础。因此,我们需要加强对管线的探测工作。管线探测的原理大多源于地球物理学的思想,将地球物理理论和勘探技术应用到勘探实际中去是本文讲述的主要内容。
Overview Geophysical prospecting is based on the difference of the physical characteristics of underground materials. By using the principle of physics, the exploration of the underground objects can be realized by observing and studying the distribution of space and time of physical fields (electromagnetic fields, magnetic fields, etc.). Put it plainly is: the use of physical differences, analysis and determine what buried in the ground. Most urban water supply pipelines are laid underground. With the development of urban construction, many topographic reference objects have been changed, and it is often difficult to determine the pipe position from the original drawings. At the same time, pipeline exploration is also to establish an urban underground pipe network database and to realize the dynamic computer network The basis of management. Therefore, we need to strengthen the exploration of the pipeline. Most of the principles of pipeline exploration come from the idea of geophysics. The application of geophysical theory and exploration technology to exploration is the main content of this paper.
