摘要

    摘要
  • 摘要: 在西北某大型填埋场边坡区域布设渗滤液水位、堆体表面位移和深层侧向位移监测点并开展现场监测。在2014年4月~8月间,受垃圾堆载、填埋作业机械动荷载和强降雨的影响,堆体边坡区域发生3次大范围滑移,最大滑移报警面积达30029 m2,最大日均表面位移253 mm,滑移深度达17 m。反分析该填埋场垃圾堆填边坡滑移全过程,掌握了除堆体水位和强降雨因素外,垃圾堆载、动荷载等因素作用下的堆体滑移规律。进一步分析迫降水位、分层压实、土工织物加固等措施的抗滑效果,结果表明,采取降水压实及土工织物加固措施可满足堆体后续堆填的稳定要求。
    Abstract: The field monitoring results from a large landfill in Northwest China are introduced. The monitoring items include leachate level, surface horizontal displacement and deep lateral displacement at the landfill. The monitoring results show that there were 3 large slips in the landfill from April to August in 2014, caused by garbage load, dynamic load and heavy rainfall. The maximum sliding area is 30029 m2 and the sliding depth is 17 m. By monitoring and back-analyzing the overall process of the slope sliding of a landfill in the Northwest region of China, the slip principles of the slope are got, that is, the factors include garbage load, dynamic load, leachate level and heavy rainfall. The antislip effects of the measures of drawdown of leachate level by pumping, stratified compaction and geotextile reinforcement are analyzed. It is shown that the requirements of stability can be satisfied when using the measures of drawdown of leachate level by pumping, compaction and geotextile reinforcement.
