垃圾卫生填埋场沉降计算分析与探讨
摘要:Sowers理论模型为国内外应用较为广泛的垃圾填埋堆体沉降计算模型，具有公式简单、参数少的特点，行业标准也推荐使用。但标准中对于相关参数取值仅给出建议的范围值或要求试验获取.在参考范围内参数取值不同直接影响到计算结果的准确性，而不同地域垃圾堆体成分均存在差异，垃圾堆体实验样本较大的离散型也决定了试验数据不易测定。因此，行业标准公式应用于具体工程时有一定的局限性和不确定性，基于北京某垃圾卫生填埋场的一系列现场监测数据，充分分析该场区垃圾堆体的沉降规律，将实测数据应用到Sowers模型有关参数的反分析确定中。将理论模型与现场实测数据相结合，为该工程垃圾堆体后续的沉降分析奠定基础，以期对类似的工程具有参考和借鉴的意义。
Abstract:As the method to predict the landfill settlement,Sowers theoretical model has been widely applied at home and abroad and also recommended by the industry Standard for ifs simple formula and less parameters. However, the industry standard formula has some limitations and uncertainties when applied to the specific project. Because it's difficult to determine the model parameter by the standard for we can only get the range value or has to test to get the specific value. Different parameter selection form the scope of the reference parameter could lead to the different prediction results. There are differences in solid waste deposits in different regions, and the test data is not easy to measure for solid waste body sample has the large discreteness. As a result,based on a series of field monitoring data at one of the Beijing waste sanitary landfill site, this article full analyses of the landfill settlement rule in the region, applied the measured data to Sowers model to determine the relevant parameters. Combining theoretical model with the field measured data, this article laid the foundation for analysis the follow-up landfill settlement,and has a reference significance for similar projects.
