地下车站盖挖逆作法施工自动化监测方案研究

Study on Automatic Monitoring Scheme of Underground Station Cover Excavation Top-down Construction

随着我国城市建设的发展,越来越多的地下轨道交通亟待修建。盖挖逆作法作为修建地下车站的一种常见施工技术,能尽可能缩短影响交通的时间,减少对周围环境的影响。地下车站大多位于城市中心,周边建筑物、管线多且密集,地质条件复杂,正在修建的超深大地下车站会对其安全产生影响。自动化监测能在地下车站修建过程中提供准确、可靠、实时的监测数据,必要时发出预警,确保施工安全进行。通过对自动化监测方案进行研究并分析测点布置情况,能对整个监测过程有更加直观清晰的了解,因此在对地下车站进行盖挖逆作法施工过程中进行自动化监测及自动化监测方案研究具有重大意义。

As the traffic problems in China's cities become more and more prominent,the construction of underground stations is an effective means to solve the current problems.Cover excavation reverse method,as a common construction technique for building underground stations,can shorten the time of affecting traffic as much as possible and reduce the impact on the surrounding environment.Underground stations are mostly located in urban centers with many and dense surrounding buildings and pipelines and complex geological conditions,which can be affected by the ongoing construction of underground stations.Automated monitoring can provide accurate,reliable and real-time monitoring data during the construction of underground stations,and issue early warnings when necessary to ensure that construction is carried out safely.Through the study of the automated monitoring scheme and the analysis of the measurement point arrangement,the whole monitoring process can be understood more intuitively and clearly,so it is of great significance to carry out the automated monitoring and the study of the automated monitoring scheme during the construction of the underground station by cover excavation and reverse work method.
