摘　　要：基坑工程中内支撑的变形监测是一项重要的工作,科学合理的监测能对基坑安全起到预警作用,更好地指导施工。介绍了用于内支撑变形监测的先进仪器的性能、使用方法以及由这种仪器组成自动化监测系统的方式,并以南京新城科技园国际研发总部园为背景,对超大圆环型内支撑在施工过程中的变形进行了数据采集和处理。结果表明:自动化监测有效地提高了监测工作的质量和精度,可为及时掌握基坑在施工过程中的变化情况和工程安全提供有力保证。In excavation engineering, monitoring of the strut deformation is an important work, scientific and reasonable monitoring work can play a role in early warning for pit safety, and can guide the construction better. In this article, we respectively introduced the performance and usage of an advanced instruments used for strut deformation monitoring, the way to composition of an automated monitoring system by this instrument. And the excavation engineering of international R＆D headquarters park in science and technology park of Nanjing new city as the background for this paper, during the construction process, the super-large ring strut system deformation data was collected and processed. The results show that, automated monitoring improved the quality and accuracy of the monitoring, and this can provide a strong guarantee to grasp the pit changes in construction process in time and to ensure engineering safety.
