填埋场垃圾堆体斜面压实工程试验研究

In situ engineering tests on MSW slope compaction effects at Xiaping sanitary landfill in Shenzhen

通过现场工程试验对填埋垃圾堆体斜面压实效果进行了影响因素的研究 .试验证明 :在垃圾填埋作业过程中 ,压实机械对填埋垃圾堆体斜面压实的效果受垃圾堆体斜面坡度、垃圾堆体构造层厚度、压实机械行程次数以及压实机械的行驶方向等因素影响显著 .实验结果表明 :为取得最佳的垃圾堆体斜面压实效果 ,斜面最佳坡度在 1∶5～ 1∶4之间 ,最佳垃圾摊铺厚度在 0 6m～ 0 7m之间 ,最佳机械行程次数为 3次 。

MSW compaction operation was an important way to increase the density of the landfilled refuse, to save the landfill capacity and to extend the lifetime of the landfill. Different factors which could influence the MSW inclined plane compaction effects were explored through in-situ engineering tests at Xiaping sanitary landfill in Shenzhen city. The results indicated that the most important factors which could influence the MSW inclined plane compaction effects were slope gradient, layer thickness, machine compaction times and driving direction during the landfill operation.
