摘　　要：桩板结构路基的桩基属于直径较大的挖孔灌注嵌岩桩，其荷载传递具有摩擦桩的特性；与土体相比．桩承担了绝大部分的动力荷载，且加载频率和激振位置对动应力有明显影响。正是由于桩基加深了这种影响，使得路基中土体的受力情况得到显著改善，从而使沉降量在工后可以满足铺设无碴轨道的要求。本文主要针时桩板结构中桩基的计算进行探讨。The pile foundation of pile-plank embankment is a kind of bored piles with large diameter, and it＇ s loading transfer has a feature of friction piles Comparing to soil, the pile has shared most of the dynamic loading. And the loading frequency and the position of tremor have effects on dynamic stress. Pile foundation expands of the dynamic impact range of the subbase and improves the loading carrying status of the soil of the sub-base. The settlement meets the requirements of the settlement in terms of construction of ballasted track, This paper discusses the calculation of pile foundation in pile-plank embankment.
