State-of-the-art:The causes of steel bar exposure defects of bored piles and remediation methods

WANG Chenghua,YANG Yanli(School of Civil Engineering,Tianjin University,Tianjin 300072,China)  
In order to eliminate the impact on bearing capacity and durability of bored piles caused by exposed reinforcing steel,in this paper,the causes of steel bar exposure are analyzed and related preventive measures are presented from the aspects of structural design,material selection and construction management for piles,moreover,some practical methods was recommended to deal with defects in different depths.On the basis,the bearing behavior assessment of the steel bar exposure defects and remediation was discussed,and the tendency of the developments in the theory and technology for the remedying defects was dressed.
