Abstract
In order to solve the design problem of single row piles in engineering,the single row piles,the pile cap and the connection beam are regarded as a whole to carry out stress analysis.First of all,"single row piles-pile cap-connection beam" integrated model is established to analyze the effects of connection beam stiffness,adjacent foundation stiffness and differential foundation settlement,and to find out the related influencing factors.Then,"single row piles-pile cap-connection beam" SAP2000 finite element model is established to reflect the combined stiffness between the pile and the connection beam through "pile-soil effect".The forced displacement load is applied to reflect the influence of differential foundation settlement,and the stress of connection beam can be read directly from the model.The case analysis shows that this method can fully demonstrate the interaction between and among the pile (pile-soil effect),the pile cap and the connection beam and the stress state of "single row piles-pile cap-connection beam" is truly reflected to make the design of the connection beam more reasonable and reliable.关键词
