This paper introduces the use of cast-in-place pile with branches and plates in the actual engineering cases,and comparison is conducted between this particular type of usage and the common use of cast-in-place pile under the same working conditions.

Compared with column bored pile,the bored pile with branches and plates is a new type of piles with higher bearing capacity and lower settlement.

Analysis on deformation characteristic of squeezed branch and plate pile under lateral load with finite element method;

The squeezed branch and plate pile is a type of special figure pile.

3D finite element analysis of pile-soil interaction of squeezed branch pile;

Finite element analysis on horizontal load performance of squeezed branch pile;

Forecasting ultimate bearing capacity of single squeezed branch pile by hyperbola method;

We designed the shaking table test of squeezed-branch piles-soil-structure dynamic interaction system.

Experimental investigation and design analysis of vertically loaded cast-in-situ pile with expanded branches and plates;

Based on the results of static loading tests and measurements of body resistance and bottom resistance of six piles, the load bearing capacity and deformation behavior of vertically loaded cast-in-situ piles with expanded branches and plates are analyzed, and several pieces of instructive conclusion are given.

Referring to the current study of cast-in-situ piles with expanded branches and plates and methods of pile foundation analysis, the paper makes a thorough research on the bearing and deformation behavior of vertically loaded piles with expanded branches and plates.
