摘要
我国北方地区,高桩码头工程中桩基采用大直径PHC管桩(管径1.2 m及以上)工程案例相对较少,可借鉴经验有限。以某工程为例,客观分析施工过程中出现的断桩、桩身纵向和环向裂缝等不同程度的破损情况,归纳总结大直径PHC管桩破坏的主要原因,提出了防止打桩时桩基破坏的改进措施及断桩、桩身裂缝的加固方案。
In northern China, there are a few project cases that the pile foundation of the high pile wharf engineering with large diameter PHC pipe pile（ diameter 1.2 m or more） .Taking a project as an example, this paper analyzes the damages such as broken piles, longitudinal and toroidal cracks on the piles, summarizes the main reasons of the pile foundation damages. It also proposes the improvement measures to prevent the damage to piles during piling, gives the repair plans of broken piles and pile crack.
