| 摘 要： | 随着PHC管桩在港口工程中的广泛应用,也逐渐暴露出该桩型的一些弱点。尤其是由于其脆性导致的开裂、断桩等现象屡见不鲜,因此,对其完整性的检测和控制显得十分重要。本研究从目前应用于基桩完整性检测的各种方法中总结规律,分析每种方法的优缺点,提出港口工程PHC管桩完整性检测的基本程序,并将其应用于长江某港口工程中,取得较好效果。

| Abstract: | Following the wide application of PHC Piles in construction of port,some weaknesses of the pile are also exposed.In particular,cracks and ruptures are not rarely seen in PHC piles due to their brittleness.Therefore it is more evidently important to detect and control the integrity of PHC piles.The authors have summarized various methods currently used for detection of integrity of piles,analyzed the advantages and disadvantages of each method,and proposed the basic detecting procedures for the PHC piles in ... |
