摘要
管桩因承载力高、稳定性强等优点得到了广泛应用,而在各领域服役过程中出现了竖向裂缝问题。为充分阐明管桩竖向裂缝产生的原因,并基于裂缝产生机理提供有效防治措施,提高管桩在不同环境下的使用寿命,解决由管桩开裂产生的各种工程问题。通过总结分析现有研究成果,对不同使用领域的管桩竖向裂缝的产生机理、裂缝危害、裂缝防治措施及裂缝检测技术进行综述,为管桩工程裂缝处理提供参考。
Pipe piles have been widely used because of their high bearing capacity and strong stability,but vertical cracks were appeared in the service process of various fields.In order to fully clarify the causes of vertical cracks happened in pipe piles,provide effective prevention and control measures based on the mechanism of cracks,improve the service life of pipe piles in different environments,and solve various engineering problems caused by pipe pile cracking.By summarizing and analyzing the existing research results,the generation mechanism,crack hazards,crack prevention measures and crack detection technology of vertical cracks in pipe piles in different fields of use are reviewed.The results can provide reference for crack treatment of pipe pile engineering.
