摘　　要：在建筑工程中,桩基础是应用非常普遍的一种基础形式。而高桩桩基作为水上交通工程的基础工程,其质量对上层建筑的安全至关重要。桩基础类型是多种多样的,有效加强桩基测量工作,在保证整体桩基工程质量上起决定性作用,是当今测量工作者研究的热点。文章针对工程测量过程中的高桩桩基工程测量施工中出现的无控制系统、投影变形、放样精度不高等问题,通过高桩桩体测量实例,对测量控制方法进行了阐述,并指出了桩基工程测量控制要点,提供思路借鉴。In construction engineering,pile foundation is a very common form of foundation.As the foundation engineering of water traffic engineering,the quality of high pile foundation is very important to the safety of superstructure.The types of pile foundation are various.It is a hot spot for the surveyors to effectively strengthen the pile foundation survey and play a decisive role in ensuring the quality of the whole pile foundation project.In this paper,aiming at the problems of no control system,projection deformation and low lofting accuracy in the construction of high pile foundation engineering survey in the process of engineering survey,the survey control method is described by taking the survey of high pile as an example,and the key points of survey control in pile foundation engineering are pointed out,which can be used for reference.
