Analysis and Process of Prestressed Concrete Pile (PHC) Accident in a Highrise Residential Building/Cai Minjun,Cai Weijuan, Wang Yaolong,Huang Wei(Shanghai Xiandai Huagai Archit. Design Co., Ltd., Shanghai 200041,China)
Abstract:According to the real quality accident of prestressed concrete pile(PHC), and
based on overall check and analysis, effective strengthening measurements to improve the quality level of the defect pile are presented. Based on the detailed calculation of bearing capacity of pile foundation, settlement and eccentricity, some piles are added to meet the requirements of the bearing capacity and normal used limitstate. The engineering loss is reduced to the minimum.
