摘要
对浙北某高速公路软基处理中3种常见桩(塑料套管桩、预应力管桩和水泥搅拌桩)的相应荷载、单桩承载力进行计算,得出其适用条件。对各种形式的桩进行经济比较,以确定最佳软基处理方案,分析、研究过程及结果可供类似工程参考。
This paper calculates corresponding loads and single-pile bearing capacity of three common piles（plastic sleeve pile,prestressed pile and cement agitation pile） in soft roadbed treatment of some ex-pressway in north Zhejiang and obtains applicable conditions.The paper compares various piles in econo-my in order to determine the optimal treatment schemes for soft roadbed.The analysis,research process and result can be referred by similar projects.
