In building construction, deep foundation as the most important point of security control must be controlled in the whole construction process. The paper researches the engineering measuring technology—deep foundation engineering monitoring. Combining with the construction case of deep foundation, it analyzes and discusses the monitoring and implementation of the horizontal displacement and layered settlement of deep soil from monitoring frequency, monitoring cycle, monitoring control indicators, monitoring method and data processing method, monitoring warning and alarm feedback measures and monitoring quality guarantees measures, hoping to be helpful for the construction and monitoring of deep foundation pit.% 在建设工程施工中，深基坑工程作为最为重要的安全控制点，必须在施工全过程中都予以重点监控。本文就近年来蓬勃发展的一项工程测量技术应用——深基坑工程的监测，结合某深基坑工程实例，从监测频率、监测周期、监测控制指标、监测方法与数据处理方法、监测预警与报警的信息反馈措施、监测质量保障措施等方面，对该深基坑工程的深层土体水平位移及分层沉降等方面的监测实施进行了浅要的分析与探讨，并希望对今后的深基坑工程施工监测工作提供一定的帮助和借鉴。
