摘　　要：土地资源紧张,很难新征用地新建填埋场,扩建增容成为解决库容不足的重要手段。本研究提出了填埋场扩建增容设计思路,基于现场监测和堆体稳定分析判定扩建增容的可行性,提出不同库容增加量的工艺比选方案,开展各方案的增容堆体稳定性验算,并结合稳定控制措施要求、投资等因素确定扩建增容方案。以成都某填埋场为例,现状堆体整体稳定安全系数为1.794~1.881,具备扩建增容的可行性。工艺比选方案一增容量为1.2×10^(6) m^(3),扩建增容后堆体整体稳定安全系数为1.481~1.713;工艺比选方案二增容量为8.0×10^(5)m^(3),扩建增容后堆体整体稳定安全系数为1.696~1.784。采取了妥善的稳定控制措施后最终选定工艺比选方案一。As land resources are scarce,there is no available space to construct new landfills,landfill expansion has become an important means of solving the shortage of storage capacity.A design concept for landfill expansion was proposed in this study.It determined the feasibility of expansion based on on-site monitoring and pile stability analysis.Different technical selection schemes for different capacity increments were presented.Stability calculations of increased capacity piles for each scheme were conducted.These calculations were combined with requirements for stability control measures,investment factors,and others to finalize the expansion plan.Taking a landfill in Chengdu as an example,the current pile had a general stability safety factor of 1.794 to 1.881,indicating the feasibility of expansion.Technical selection scheme one achieved an increase of 1.2 million cubic meters,with the general stability safety factor of the increased capacity pile ranging from 1.481 to 1.713 after the expansion.Technical selection scheme two achieved an increase of 0.8 million cubic meters,with the general stability safety factor of the increased capacity pile after the expansion being 1.696 to 1.784.After adopting appropriate stability control measures,scheme one was selected for implementation.
