中国东南部地区城市垃圾填埋场的环境岩土工程问题及其对策(英文)

东南部是中国经济最发达和人口密度最高的地区之一,因此城市垃圾堆放和处理已成为日益迫切的社会问题。对于一个发展中的国家,卫生填埋是城市垃圾处置的主要途径。本文首先回顾了中国城市垃圾卫生填埋处理的4个阶段;对比了城市垃圾卫生填埋、焚烧、堆肥3种处理方法的费用;提供了中国东南部地区城市垃圾的组成、增长和处理的相关数据;根据垃圾填埋场的地貌特征、地质环境和地质结构,对我国东南部地区城市垃圾卫生填埋场进行了分类,即丘陵型、平原型、滨海或河滨型和矿山型4类,并对这4类垃圾卫生填埋场的主要环境岩土工程问题进行了分析和探讨,最后对这些问题提出了相应的对策和今后的工作内容。

Environmental Geotechnical Problems and Their Treatment of Municipal Sanitary Landfills in the Southeast of China

The Southeast of China is the most developed zone with the highest population density in China. It is a very urgent social problem how to treat so large amount of municipal solid waste (MSW). At present, the sanitary landfill is a main way to solve this problem. In this paper, the main environmental geotechnical problems of the current sanitary landfills is analyzed and discussed based on the in-site investigation. In the light of the topographic characters and geological conditions, the sanitary landfill sites can be divided into four types, i.e. hilly, plain, riverine or coastal and mining. Each type of landfill is described and discussed; finally, the stategies to solve these problems are put forward.
