【摘要】：城市垃圾填埋是城市垃圾处置中最根本的办法。虽然现在经常使用堆肥、焚化或者分选回收的方法来处理城市的垃圾,但仍需作最后的填埋处理来处理掉其中较难去除的部分及残留物质.环境地球物理学(EnvironmentalGeophysics),是一门由环境学科与地球物理学相辅相成,且融合各自特点的综合交叉性学科,它的研究重点主要是应用地球物理学中的观点和措施来将地球物理场和地下介质的物物性与人类生活环境联系起来。在解决城市生活垃圾填埋等相关问题的过程中,物探方法和技术以其特有的优势发挥着越来越重要的作用,并随着物探技术的进步和数据处理方法的提高,已经成为城市垃圾治理等方面一项不可缺少的重要手段。本文研究内容主要是采用高密度电阻率法、探地雷达法、高精度磁测法和瑞雷面波法等四种地球物理方法对北京亦庄开发区北神树垃圾填埋场附近某工区(N39°48.055,E116°32.021)进行了实际勘测,共布设11条均为北偏东60°的测线,每条测线实测长度为250米(其中350线为115米),利用地球物理原理来研究垃圾填埋场地区地下介质埋藏分布以及垃圾污染对地下介质的地球物理场的物理特性造成的变化。通过多种方法的数据采集,得到了垃圾填埋场地球物理检测的第一手资料,对获得的数据运用多种地球物理数据处理软件进行了系统处理,并在实地进行钻探研究,进行对比以期寻找相对准确的物探方法。通过以上研究,获得以下结论:其中高密度电阻率法对工区内低、高阻污染区域的区分度较好;探地雷达法对于浅部垃圾的大致分布有较好的探测;高精度磁测法对于弱磁性的生活垃圾的探测效果不理想;面波法能够较好地反映出工区的地下地层分布和构造。由高密度电法和瑞雷面波法测量结果可判断,地下疑似存在少量埋藏废弃物,且存在由于垃圾渗滤液造成的污染区;结合对工区实际观察,发现工区存在两条地地下水泥管道,因此这两种方法较为适合于城市垃圾填埋情况的检测。
[Abstract]:Landfill is the most fundamental method in the disposal of municipal waste. Although composting incineration or sorting and recycling are often used to dispose of municipal waste final landfills are needed to dispose of the more difficult parts and residues. Environmental Geophysics (ESP) is a comprehensive cross-disciplinary subject, which is complemented by the environmental discipline and geophysics, and integrates their own characteristics. Its main research focus is to apply the viewpoints and measures of geophysics to connect the physical properties of geophysical fields and underground media with the living environment of human beings. In the process of solving the problems of municipal solid waste landfill and other related problems, geophysical exploration methods and techniques play a more and more important role because of their unique advantages, and with the progress of geophysical exploration technology and the improvement of data processing methods, Has become an indispensable and important means of urban garbage treatment and so on. In this paper, four geophysical methods, high density resistivity method, ground penetrating radar method, high precision magnetic measurement method and Rayleigh wave method, are mainly used to survey a working area (N39 掳48.055U E116 掳32.021) near Beishenshu Landfill site in Beijing Yizhuang Development Zone. A total of 11 survey lines were set up, all of which were 60 掳NE. The measured length of each line is 250 meters (among which 350 lines are 115 meters). The buried distribution of underground media in landfill area and the change of geophysical properties caused by garbage pollution on the geophysical field of underground media are studied by using geophysical principles. Through the data collection of various methods, the first-hand data of geophysical detection in landfill are obtained, and the obtained data are systematically processed by using a variety of geophysical data processing software, and drilling research is carried out in the field. A comparison was made to find a relatively accurate geophysical method. Through the above research, the following conclusions are obtained: the high density resistivity method can distinguish the low and high resistance pollution areas, and the ground penetrating radar method can detect the distribution of shallow garbage. The high precision magnetic measurement method is not effective in detecting the weak magnetic solid waste, and the surface wave method can well reflect the distribution and structure of underground strata in the working area. From the measurement results of high density electric method and Rayleigh surface wave method, it can be concluded that there are a small amount of buried waste and contaminated area caused by landfill leachate, and two underground cement pipelines are found in the working area. Therefore, these two methods are more suitable for the detection of municipal solid waste landfill.
