威海是＂最适宜人类居住的地方＂,但随着城市建设的快速发展,城市垃圾产生量不断增加,垃圾填埋场选址问题亟待解决。以威海市环翠区为研究对象,综合考虑地形地貌、土地利用规划、交通、水利规划、气象、地质、水文地质、工程地质、环境地质等多方面因素及经济效益和环境效益,从地质环境角度出发,选取5个层次共15个评价因子,采用层次—网格法进行了垃圾填埋场选址区划分析研究,划分出垃圾可填埋区、限制填埋区、禁止填埋区。并在限制填埋区和可填埋区,进一步优选出几个垃圾填埋场地的首选场址,可供规划、设计部门参考。 相似文献

正确分析评价垃圾填埋场的地质特征和防渗方案,对垃圾填埋场的选址、设计以及施工运营极为重要。从自然环境、地层结构及岩性特征等方面阐述了淮安市某垃圾填埋场的地质特征,分析了填埋区含水层分布、厚度、赋水性等水文地质条件;结合室内试验和野外试验,综合确定了填埋区岩土层渗透系数大于1×10^-7cm／s,表明填埋区不具备天然防渗的条件,需采用人工防渗系统才能有效的阻滞垃圾渗滤液对周边环境的影响。 相似文献

岩溶地区的垃圾填埋选址较为困难,现行的垃圾填埋场选址评价方法又存在较大局限。笔者等依据垃圾填埋场的建设宗旨和选址基本原则,结合岩溶地区的环境地质特点,探讨提出一套适用于岩溶地区的垃圾填埋场选址评价方法。通过实例应用表明,该方法可在现行较难选出垃圾填埋场的岩溶地区,优选出适宜性较好的未来垃圾填埋场,能够担当起解决岩溶地区的垃圾无害化、减量化填埋处置的难题和重任。 相似文献

当今采矿业仍然使用全陷法开采,致使矿区环境遭到十分强烈的破坏。为了环境保护的需要,德国等许多国家积极开展利用废物进行地下充填的新的采矿法,使矿区环境得到保护以及采矿业达到可持续发展。文中以德国鲁尔矿区为例,充分论述了矿区的地质和水文地质条件对地下填埋场或地下充填场选址的约束,以及如何对矿床的地质和水文地质条件进行充分调查和分析,优选出安全可靠的固体废物的地下填埋场或地下充填场地,使采矿业的发展和环境保护的需求之间达到最优化的联合。重点介绍了德国地下填埋场的充填技术,适合于地下充填废物的筛选;对地下填埋场选址的地质条件约束,主要通过地质、岩性、地质构造分析和水文地质条件约束来确定,最后优选出最安全的地下填埋场。 相似文献

Identification of hazardous waste landfill site: a case study from Zanjan province, Iran 总被引：2，自引：2，他引：0

The study of landfill sites is one of the most important studies in landfill engineering, and the landfill site selection
involves combination of engineering, science, and politics. This paper describes a comprehensive hazardous waste landfill
site selection methodology with the combined utilization of geographic information system and multiple criteria analysis methods,
as applied to the Zanjan province in Iran. The six main data categories that were used are geological/engineering geological,
geomorphological, hydrological/hydrogeological, climatological, pedological, and social/economical criteria, which included
31 input layers in total. A suitability map for hazardous waste landfilling was prepared for study area with five classes
from most suitable to completely unsuitable. Finally, out of the three sites, one site was selected which was chosen by the
local authorities. Our work offers a comprehensive methodology and provides essential support for decision-makers in the assessment
of hazardous waste management problems in Zanjan province in I.R. Iran and other developing cities in other countries. 相似文献

Engineering geological aspects of replacing a solid waste disposal site with a sanitary landfill 总被引：1，自引：0，他引：1
Kamil Kayabali 《Engineering Geology》1996,44(1-4):203-212
The current solid waste disposal site in the Mamak district of Ankara is being engulfed by the growing city. All varieties of solid wastes, including medical wastes, are stored at the present site in an irregular manner. Topographical and geological conditions at Mamak waste site are favorable for constructing a sanitary landfill. Located at the edge of a topographical depression, the site is underlain by the natural hydraulic barriers such as clay and metagreywacke. The terrestrial clay has a permeability of 10−7 to 10−8 cm/s and low to moderate values of CEC. The proposed sanitary landfill to replace the present solid waste site has a capacity of storing solid waste over 50 years. The details of base liner, final cover, toe embankment, and drainage of leachate and gas are presented in the paper. 相似文献

深圳坂银通道鸡公山隧道的设计路线下穿了深圳下坪固体废弃物填埋场,由于钻孔分析等前期地质勘察无法在该区域开展,下穿填埋场隧道区段施工存在地质状况不明、填埋场渗滤液及填埋气泄露等风险,现有隧道施工超前预报体系不适用于隧道下穿填埋场引发环境灾害问题。针对该难题,本文基于地震预报法(TGP)、瞬变电磁法(TEM)、超前钻孔、取样化学分析等多种方法,构建了隧道下穿填埋场施工超前地质预报体系,并对下穿填埋场隧道区段的围岩质量和渗滤液、填埋气渗漏情况进行了探测与综合分析。结果表明:(1)综合超前预报方法能够提高隧道前方围岩级别判定准确性;(2)填埋场下方存在联通至隧道施工区域的潜在渗滤液渗流通道,但尚未有渗滤液下渗情况发生,隧道开挖过程也无有毒有害气体逸出;(3)针对渗滤液渗漏风险隧道区段,采取全包防水和提升防渗材料等级等方式,可有效保障隧道施工与运营安全。本文研究成果可为隧道穿越环境风险区域施工的超前预报工作提供参考借鉴。 相似文献

An engineering geological investigation has been undertaken of a proposed landfill site in coastal southwestern Ghana which
is characterized by torrential rains, high relative humidity, shallow groundwater conditions and almost surrounded by a ridge.
The study shows that the site has some desirable characteristics such as availability of suitable soils for the construction
of the capping and bottom liners of the landfill, a large tract of land for landfilling operation and its location close to
a major highway. However, the groundwater table was shallow and there was a high potential for leachate intrusion into and
consequent contamination of nearby groundwater abstraction wells and surface potable water sources thereby constituting serious
threat to life. Construction costs could be prohibitive as extensive dewatering and backfilling of vast portions of the project
site would be required to enable the provision of a separation between the shallow water table and the bottom of the landfill.
