高速铁路深厚松软土地区新型长短桩施工技术

The new long and short piles construction technology in high speed railway deep soft soil area

以郑徐铁路客运专线永城北站软基处理为例,介绍了该路基试验段新型长短桩施工的工程特点,并对长短桩施工的具体工艺流程及其操作要点进行了详细分析,以确保高速铁路软基处理长短桩施工的安全进行。

Taking the soft foundation treatment of north Yongcheng station of Zheng-Xu railway passenger dedicated line as an example,this pa-per introduced the engineering characteristics of new long and short piles construction of this sub-grade experimental section,and analyzed in de-tail the specific construction technology and its operation key points of long and short pile construction,in order to ensure the safety of high speed railway soft foundation treatment of long and short pile construction.
