地下空间地籍调查三维地震勘探技术应用研究
|
摘要
地下空间是城市发展中土地资源综合利用的重要途径,准确掌握地下空间利用现状对城市地下地籍调查和权属认定意义重大。地下空间情况复杂,地球物理探测面临诸多现实难题。通常布置二维剖面只能对地下空间进行"拼凑式"成像,无法整体刻画地下空间。三维地震技术以全方位获取反射信号,能准确对目标对象予以成像,但目前尚无应用于城市地下地籍调查的实践。结合专题研究,以小块体、浅层采集等方法,以实现该技术在地下空间调查中的应用。通过具体实验,初步形成了实施技术方案,并对应用效果与存在问题进行了分析。
Underground space is an important way of the comprehensive utilization of land resources in urban development.To grasp the accurate information of the use of underground space is important for the urban underground cadastral survey and ownership identification.Underground space includes the underground facilities,building foundations and structure of the surrounding strata,the situation is very complicated.Geophysical detection of underground space is the difficult problem of the urban geological survey.Usually two-dimensional layout of the underground space profile can only achieve a "patchwork-type" image,not the overall characterization of underground space.3D seismic technology to obtain the reflected signal fully,can accurately image geological bodies.However,by far we still are not well put 3D seismic technology into being used in urban geological survey.We carry out special research projects to capture three-dimensional seismic technology in the investigation of underground space by the way of small body,shallow data acquisition.We have combined a set of technical ideas,made some results on key issues,but there are some difficulties to be overcome.
