The Co-Affect Analysis And Applied Research Of The Compound System Of The Single Foundation Under Column And The Raft-Board

The reinforcement concrete Raft foundation is a type of foundation used wildly in the high-rise building. Nowadays there are some problems in the design of the Raft foundation from computation to construction to solve.Base on the mechanical analysis of the single foundation under column~ raft foundation. and the finite element analysis of the columnaft foundation and the result of the model experiment ,according as the pipeline of the columnaft foundation and the characteristic of the strength extend part of the column ,this paper presents the concept of the compound system composed of the single foundation under column and the raft-board foundation; and make a extended research;make sure how the reinforced pare under column ,the raft-board and the ground rigidity and other factor influence the ground resistence distribute;get a applied computing method of the column-raft foundation .The economic analysis and the example of the used building are both indicate that the columnaft foundation is advanced and economy.
