A STUDY ON VERTICAL LOAD BEARING PERFORMANCES OF PREFAB PILES
预制桩竖向承载性能设计理论研究

A new method is presented to analyze the vertical load bearing performances of prefab piles with optimization and back analysis techniques. In combination with optimization theory, back analysis method and a new improved elastic theory method, a program is developed not only to stimulate the load settlement curve( Q S curve) of static load testing, but also to analyze the soil mechanical parameters around the pile by using back analysis method with optimization techniques on the basis of measured load settlement information of static testing.This technique has been verified in large numbers of practical engineering with satisfactory results.
