Abstract:The article introduces the application of bracing of deep foundation pit in Chaoyang Square. The compound soil nailed wall and pre-stressed anchor rod was adopted for the upside and underside wall separately. Soil nailed wall was economical. And in the design, the third layer of soil nail wall was replaced with pre-stressed soil nail to effectively restrict the displacement of the top of soil nailed wall. Monitoring spot was laid on the top of soil nailed wall and the top of pile to measure distortion with theodolite, and all the data measured is in permitted scope of criterion.

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.
