| 摘 要： | 从热力学的角度阐述了填埋体生物降解沉降的物理机理。依此对卫生填埋场生物降解沉降进行了界定,并初步建立了生物降解沉降量的计算模型。利用该模型,根据相关实测资料,对香港某卫生填埋场内因固体废弃物生物降解产生的沉降量进行了估算,并将估算结果与该填埋场的实测总沉降量进行了比较。

| Abstract: | On the basis of thermodynamics, the physical mechanism of biodegradation-caused settlement of municipal solid waste is discussed. Furthermore, the biodegradation-caused settlement is identified; and its calculational model is initially established. According to correlative observed data, the biodegradation-caused settlement of certain sanitary landfill of Hong Kong is estimated with this method. The results are compared with its observed total settlement. |
