摘　　要：随着我国城市和经济的快速发展,生活垃圾产生量逐年递增。由于居民环保意识提高和邻避效应等因素,填埋场选址和建设越来越困难。如何利用现有填埋场增加库容,延长使用时间,显得尤其重要。结合填埋场实际运行经验,介绍了多种填埋场扩容方式及其适用性。通过某平原型填埋场扩容工程实例,采取控制边坡坡度和土工加筋等多种措施,计算扩容堆体边坡稳定性,满足规范要求。通过扩容,填埋场增加了库容7.76×10^(5)m^(3),延长了使用时间。With the rapid development of cities and economy in China,the output of municipal solid waste(MSW)is increasing year by year.Due to the improvement of residents’environmental awareness and the NIMBY effect,it is more and more difficult to locate and construct the landfill.How to increase the storage capacity and prolong the service life of the existing landfill is particularly important.Based on the practical experience of landfill operation,several ways of capacity increasing of landfill and their applicability was introduced.Through the example of a plain-type landfill capacity expansion project,various measures such as slope control and geotechnical reinforcement were adopted to calculate the slope stability of the expanded pile,which met the requirements of the specification.Through the expansion,the storage capacity was increased by 7.76×10^(5)m^(3),and the use time of the landfill site was extended.
