Through analyzing the calculation methods for the bearing capability of composite foundation with multi-type piles, the reliability probabilistic analytical model of the bearing capability of a composite foundation with multi-type compound piles are set up.

Testing study on bearing characteristics of multi-type-pile composite foundation;

Field test of multi-type-pile composite foundation;

On Haikou power plant the third phase project in bordering on sea zone,this paper optimizes the foundation treatment pattern,confirm the feasible type of pile—the drill perfusion pile with impacting slurry later basing on the experience of first and second phase p.

Through analyzing and discussing of factors affecting the selection of pile type and technology,such factors depending on the structure type,loading property,function of pile,subgrade condition,soil of bearing struatum,underground water level.

Based on technical economic analysis of changing pile type in a design of a certain foundation engineering, this article deals with the quality reliability of manual drilling cast piles used in the soft foundation.

By taking the technical and economic analyses of pile type changing in certain foundation project as an example it is stated herein that in foundation design all possible plans must be considered.
