摘　　要：随着北京市地下水位逐年升高,运营地铁渗漏水病害问题日益凸显。为了精准预测和预警渗漏病害,确保既有地铁结构的健康,从地铁结构发生渗漏病害的源头出发,采用自动化实时监测技术对地下水进行监测。基于“水位与水压直接相关,测出水压即可推算出水头高度,进而推算出水位标高”的基本原理,搭建了既有地铁结构渗漏监测预警平台,并通过对比分析自动化实时监测系统数据与原设计水位数据和水务局数据,验证了监测数据的准确性以及监测平台的预警效果。With the groundwater level rise in Beijing year by year,the problem of water leakage in subway has become increasingly prominent.In order to accurately predict and early-warning leakage diseases and ensure the safety of existing subway structures,the automatic real-time monitoring technology is used to monitor groundwater from the source of subway structures.Based on the basic principle of"the water level is directly related to the water pressure so that the water head height can be calculated by measuring the water pressure to calculate the water level elevation",the existing subway structure leakage monitoring and warning platform is built.The accuracy of the monitoring data and the early warning effect are verified by comparing and analyzing the automatic real-time monitoring system data with the original design water level data and water authority data.
