摘　　要：某高层住宅楼基础采用PHC管桩,基坑开挖后发现16根Ⅲ类桩且有横向裂缝。经分析是由大吨位压桩机强行压桩、地质条件不良、终压条件选择不当等原因造成的。Among the PHC piles used in a high rise residence foundation, 16 piles of Category Ⅲ were found with transversal cracks after foundation excavation. Analysis determined that they were caused by the forced press of heavy pile pressing machine, bad geological condition and improper stop pressing conditions and etc.
