Application and Analysis of Expanded Branches and Plates Pile in Jiaxing Area

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.
