摘要
PHC桩在沉桩过程中经常出现纵向裂缝，桩直径越大、锤型越重产生纵向裂缝的几率越大。通过对沉桩过程中的作用机理进行分析．提出采用外加钢抱箍的工程措施可以有效避免纵向裂缝的产生。
Longitudinal cracks of PHC piles often occur during pile driving. The larger the pile＇ s diameter and tile heavier lhe hanuner is, the greater the probability of the occurrence of the longitudinal cracks will be. Based on the analysis of the pile driving mechanism, we propose to adopt PHC piles plus steel hoop to prevent effectively the longitudinal cracks in pile driving.
