Optimum Design of Pile Raft Foundation on Pile-Soil Interaction

Abstract:

At present, great progress had been achieved in the theoretical research of pile-soil interaction. The principle for “main structure, secondly calculation” was traditionally adopted in engineering practice, “Full pile layout” and “Equal capacity pile layout” were still the basic pile layouts. An optimal unification was not reached among economy,safety and reasonable of building, plenty of capital and material were wasted,and unsafe hidden dangers were showed in engineering.Therefore, influences of raft thickness and different pile layouts for raft settlement and pile top reaction were analyzed by ANSYS in this paper,mechanical behavior and interaction mechanism beteewn pile raft foundation were researched. Pile raft foundation was designed optimally by using the optimization method of pumping pile. Finally, many significant conclusions were put forward.
