To compare with former calculating methods of load transfer for single pile,some improvements are made as followe:(1)The generalized load transfer model is used for pile-side and pile-tip;(2)The Rusch model of concrete is introduced to consider the elastic-plastic characteristics of pile shaft under the heavy load;(3)The Mindlin s solution is coupled up to calculate the settlement in pile-tip.

Development of application program for pile-base test with load transfer method;

Study Bearing Capacity of Revolving Digging Cast-in-Place Bored Pile Through Load Transfer Method;

This approach calculates the settlement based on the load transfer method under itself working load of pile top,according to the shear displacement theory and taking into account the interaction of group piles,it modifies the displacement-influence factor,then the settlement under adjacent pile working load on the top is calculgted,a calculation of th.

The mechanical properties of the super-long foundation piles of Tianxingzhou Bridge are analyzed by Load-Transfer Method and also by Finite-Element Method,the result shows that the top load is mainly borne by the side friction resistance of the piles.

Based on the load-transfer methods,a new method is proposed to estimate th.

A pile foundation analysis approach that combines both the finite element and load-transfer methods is presented.
