应用深层搅拌法处理素填土路基

Treating plain fill roadbed with deep stirring

结合某科学城科学大道道路排水工程实例 ,介绍了深层搅拌法加固素填土路基的机理 ,阐述了水泥深层搅拌法中水法土的物理及力学性质 ;提出了施工技术参数 ,制定出施工工艺 ,最后论述了用该种方法处理素填土的方案设计 ,桩型确定、桩的沉降及单桩承载力和复合地基承载力等问题。

Combining the instance of road drainage engineering of a science stree t in a science city, the mechanics of strengthening plain fill roadbed with deep stirring are introduced. Physical and dynamic characteristics of diaspore in ce ment deep stirring are stated. The parameter of construction technique is put fo rward, construction technology is drawn out, at last, plan design, determination of pile type, the settlement of piles, bearing capacity of single pile, compoun d ground which disposal plain fill by this mean are discussed.
