Abstract
Taking the pile foundation project of a factory building as an example,the mechanical properties of PHC pipe pile and punched pile under horizontal static load are compared and analyzed.The results show that the relation curves between the ratio coefficient m and△ Y/△H and the relation between Y and H of the horizontal resistance coefficient of the perforated pile and the prestressed concrete pile under the horizontal load show an approximate first rapid decline,then a slow decline and finally a stable phenomenon.The m-Y curves of both perforated pile and prestressed concrete pile can be divided into elastic stage,elastoplastic stage and plastic stage.The horizontal critical load and ultimate horizontal bearing capacity of perforated pile and prestressed concrete pipe pile are similar.Compared with the perforated pile,the prestressed concrete pile has better horizontal bearing capacity.关键词
