Ⅳ级自重湿陷性黄土场地长桩竖向承载力试验研究

Experamentil study on horizontal bearing capacity of long-pile in Ⅳ class collapsible loess region

利用有限元模拟理论,分析了在大厚度湿陷性黄土场地中,长桩的桩周土在天然状态和浸水状态下对基桩承载性状的作用,并对湿陷过程中桩的承载机理等进行研究,为同类地质上的工程应用提供了宝贵的技术参数。

Using theory of finite eleme nt simulation,an analysis of the soil is done for the long-pile which react the character of the pile bearing capacity in the natural state and water saturated state in the thick collapsible loess region.And a study of the load-bearing mechanism of the pile is done in collapsibility process,which would provide valuable technical parameters for similar geological projects.
