Abstract: more and more developed urban transport , rail transport is widely adopted and effective urban transport , and rail traffic network planning and construction , resulting in new lines and operating lines overlap is inevitable. Since construction of new line construction close interaction is very complex, and therefore how to reduce construction disturbance , to ensure the smooth construction of new line structure , while ensuring the safety of the existing lines , normal operation , so the subway construction process has become a very timely monitoring important topic. In this paper, Beijing Metro Line station Xuanwu Xuanwu second line beneath the existing station , for example, the implementation of research and exploration 24 hours monitoring system, an accurate grasp of the surrounding soil during the construction of new lines and adjacent underground station structures existing settlement and deformation characteristics under the guidance of wear for the design, construction , and provide a reference for future similar projects , this system includes the following aspects of the core. ( 1 ) According to subway construction, the decomposition of the phase control indicators in the control software designed early warning and alarm functions. ( 2 ) by means of pre-designed remote automatic monitoring system , the choice of using the required accuracy inclinometer , static water level, displacement meter and other monitoring equipment on existing stations and rail lines for civil structures displacement, settlement and deformation monitoring . ( 3 ) After the scene automated remote monitoring data , combined with the construction unit of the monitoring data , the city subway station construction method Shallow structure of the overlying both comprehensive and systematic analysis of the final result obtained for each step of excavation settlement or deformation structure representing both the proportion of the total settlement or deformation . ( 4 ) Automatic monitoring data on the construction has played a good role in guiding . In settling too fast, timely warning and adopt response measures to abate the negative impact on the trend , reducing the circuit structure of the old and new structures.
