Numerical Simulation Analysis of a New Pressured Multi-Branch Bored Pile
Pressured multi-branch bored pile is a new pile on the basis of squeezed branch reaming pile improved, it is a new pile technology focus on many advantages of the static pile, driven cast-in-place pile, belled pile and multi-branch bored pile. Pressured multi-branch bored pile has high bearing capacity, small settlement, cost-effective advantages of better. Numerical simulation of pressured double-branch pile on the vertical compression with ANSYS finite element analysis software obtained the alternate variation of the lateral friction and tip resistance of pile under the vertical load. Many branch of pile constitute multi-pivot friction and end-bearing pile, the bearing branch bear mainly bear vertical load, above branch force greater than the following branch. It is proposed recommended value about the vertical critical spacing of branch and the level spacing of pressured branch pile.
