Combining with factual examples,the paper introduces the process and methods for the pile foundation construction measure lofting from the accurate guide pile coordinate,extracting pile code,transferring coordinate document formats,inputting pile coordinate into total sta-tion,so as to improve the pile lofting and ensure the accuracy of the pile coordinate.%结合具体实例，从精确定位桩坐标、提取桩编号、转换坐标文件格式、将桩位坐标输入全站仪四个方面出发，介绍了桩基施工测量放样的过程与方法，以提高桩位放样的效率，确保桩位坐标的准确性。
