摘　　要：以某建筑工程为例,探究了基于PHC管桩的深基坑支护方法。在支护施工的准备阶段,做好平整场地、测量放样等工作,确保桩位精确,同时检查确认PHC管桩的质量合格;在支护施工中加强吊装、压桩、接桩等技术要点的控制,提高成桩质量;施工后做好实时监测,及时处理异常沉降等问题,保证支护安全。对于施工中常见的管桩压入难度大、桩身发生倾斜或位移等问题,应了解其成因并采取相应的防控措施,切实提高深基坑支护施工质量。Taking a certain construction project as an example,this paper explores the deep foundation pit support method based on PHC pipe piles.In the preparation stage of support construction,ido a good job of site leveling,measurement and lofting to ensure that the pile position is accurate,,and at the same time check the quality of PHC pipe piles;Strengthen the control of technical key points such as lifting,pile pressing,and pile connection during construction,and improve the quality of pile formation;Real time monitoring should be carried out after construction to promptly address issues such as abnormal settlement and ensure support safety.For common problems such as difficulty in pressing pipe piles and tilting or displacement of pile bodies during construction,it is necessary to understand their causes and take corresponding prevention and control measures to effectively improve the quality of deep foundation pit support construction.
