| 中文摘要:嘉兴地区为典型的湖积平原，第四系地层具有多个明显“软-硬”交替的沉积旋回。目前该地区的重大建筑物一般都采用预应力管桩或钻孔灌注桩，而挤扩支盘桩可以利用在桩身不同部位设置分支或承力盘，从而充分发挥地基土各硬土的承载能力，提高单桩承载力，节省造价。结合嘉兴地区的地层特征及挤扩支盘桩的受力承载机理，认为挤扩支盘桩可以作为嘉兴地区一种新型的桩基形式。 |

| Abstract:Jiaxing area belongs to representative lacustrine plain zone.Its Quaternary period stratum has several evident sediment cycles "soft to hard".Pre-stressed concrete pipe piles and bored cast-in-place piles are adopted in big important buildings.But expanded branches and plates pile can make use of its branches and plates in different parts to give full play to the bearing capacity of each hard layer to increase the bearing capacity of single pile with lower cost.According to the stratum characters and bearing mechanism,expanded branches and plates pile is considered a new type of foundation pile in Jiaxing area. |
