【Abstract】 This paper presents the issues that encountered in the jacked Pre-stressed High Strength Concrete(PHC) pile for a high-raised building.These abnormal problems,such as,pile shaft burst due to excessive compression pressure;broken pile head;significantly higher than the target pile tip elevation as well as burst of groundwater after the pile installation,are discussed in the paper.Measures that mitigate these abnormals are also proposed.更多还原
