摘　　要：针对北京市南水北调东干渠工程凉水河段垃圾填埋场浅层及深层土壤的有害、危险气体浓度分布特征进行研究,分析结果表明:垃圾填埋场土壤环境中O2浓度均偏低,CO2浓度、CH4浓度检出超标范围较大,土壤环境属还原环境;VOCs浓度较高主要与微生物分解土壤环境中有机物等行为有关。在施工过程中可能因为隧道开挖而导致有害、危险气体富集进而导致有害、危险气体浓度过高现象,施工中务必做好通风等防护工作。土壤有害、危险气体环境分析为工程设计、施工等提供安全咨询工作。The concentration of deleterious and dangerous gas in shallow and deep soil of landfill in the Liangshui river section of east main canal project was studied. The results indicate that the concentration of oxygen in landfill is relative low, the concentration of carbon dioxide and methane are out of range, the soil environment belongs to reducing environment, high concentration of VOCs is related to decomposition of organic matter by microbes in soil. The high concentration of deleterious and dangerous gas in soil probably results from the gathering of these gases during tunnel construction; therefore we should pay attention to air ventilation in the construction. The analysis of environment of deleterious and dangerous gas in soil provides the reference to the engineering plan and construction.
