本文介绍了有机废物填埋场在正常运行条件下的温度监测程序的结果。该程序的目的是捕获细胞内不同位置的温度随时间的变化。在 20 个月的时间内，对细胞中心体内两个层面的温度进行了测量。那段时间获得的结果表明，温度在最初几周内上升，然后在几个月后下降到稳定值。监测计划开始时，垃圾填埋场底部附近（基线上方 2 m）的峰值温度平均为 60 摄氏度，8 个月后稳定至 53 摄氏度。第二道海拔高度（基线以上 4 m）的峰值温度平均为 57 摄氏度，13 个月后趋于稳定至 55 摄氏度。靠近电池底部测得的温度表明衬里系统承受高温，超出了测试和设计期间通常考虑的温度范围。这一观察结果强调了从液压角度和耐用性角度考虑温度变化对不同衬里系统组件性能可能产生的影响的重要性。 DOI：10.1061/(ASCE)GT.1943-5606.0000533。 (C) 2011 年美国土木工程师学会。
This paper presents the results of a temperature-monitoring program in an organic-waste landfill cell under normal operating conditions. The aim of the program was to capture the temporal evolution of temperature at various locations within the cell. Temperatures were measured at two levels within the central body of the cell over a period of 20 months. The results obtained over that period of time indicate that the temperatures increased within the first few weeks, then decreased to a stable value after a few months. The peak temperatures near the base of the landfill cell (2 m above base liner) averaged 60 degrees C at the start of the monitoring program and leveled off to 53 degrees C after 8 months. The peak temperatures in the second lift (4 m above base liner) averaged 57 degrees C and leveled off to 55 degrees C after 13 months. The temperatures taken close to the base of the cell indicate that the lining system is subjected to high temperatures, outside the range of temperature typically considered during testing and design. This observation highlights the importance of considering the possible impact of the changes in temperature on the performance of the different liner system components from both the hydraulic view point and durability.
