以商洛市环城北路西施坡隧道为工程实例，介绍了隧道的动态监测技术，对典型断面的数据进行了回归分析，并采用AN-SYS有限元软件，对隧道断面的开挖支护进行了数值模拟，将数值分析结果与实际监测数据进行了比较，以更好地指导施工和优化设计。%Setting Shangluo North Huancheng Road Xishipo tunnel as the engineering example, the paper introduces the technology of the dy-namic monitoring of the tunnel, and analysis the monitoring data of typical sections. At the same time, it utilizes the simulation software ANSYS to analyze the monitoring data of the typical cross-section, then comparing with the actual monitoring data, so as to guide the construction and optimize the design.
