摘　　要：结合位于中东燥热地区的超高层办公楼项目——AL Hikma Tower,研究了阿联酋燥热临海地区桩基负极保护施工技术。该技术是针对施工初期桩头剔凿时发现桩头钢筋外露现象提出的,即利用电化学保护方法阻止桩基钢筋腐蚀。介绍了该技术的特点、适用范围、原理、施工工艺、机具设备、质量控制措施、安全措施、环境保护措施等。实践证明,外加电流负极保护法的实施不仅攻克了工程遇到的巨大技术难关,保证项目基础顺利施工,而且社会和经济效益非常显著。Based on AL Hikma Tower project in middle east,this paper researched the cathodic protection pile in hot coastal areas.According to the steel bars exposing at early construction stage when pile top chiseling,the electrochemical protection method is used to prevent corrosion of pile steel bars.The key points of the technology are introduced including features,using range,principle,construction technology,equipments,quality control,safety measures and environmental protection measures.It proves that the cathodic protection pile method in hot coastal areas solved the technical difficulties and ensured the foundation construction with good social and economical benefits.
