水泥土搅拌桩在垃圾卫生填埋场工程边坡加固及地基处理中的应用

The Application of the Cement Mixing Method in Landfill Slope Reinforcement and Ground Treatment

随着环卫事业的快速发展,越来越多的生活垃圾卫生填埋场建造在由深厚软土组成的软弱地基上。工程经验表明,制约这类工程实施成功与否的关键因素是填埋场库区开挖边坡的整体稳定性、围隔堤和库底的地基承载力及不均匀沉降控制。结合某生活垃圾卫生填埋场填埋库区工程,介绍了水泥土搅拌桩加固软土地基边坡和库底的应用,对该工程开挖边坡整体稳定性和加固后复合地基承载力进行了理论分析,为众多沿海地区软土地基垃圾卫生填埋场设计提供一种思路。

With the rapid development of the sanitation services,more and more landfills are built in the soft ground which are composed of deep soft clay.Engineering experiences show that the stability of excavation slope,the bearing capacity and control of the differential settlement of barricading dike and reservoir bottom are the key factors to the success of these project.This paper combined with some of the landfill site project,the application of the cement mixing method to the reinforce soft soil foundation of slope and reservoir bottom were introduced.And we analyzed the stability of excavation slope and the bearing capacity of composite foundation.This can provide a new thought to the landfill design of the coastal regions which are in soft soil foundation.
