摘要
随着社会经济的高速发展,越来越多的城市开始修建地铁.城市地铁区间等地下工程往往要穿越既有的建(构)筑物以及燃气管道等市政管线.地铁安全文明施工要求高,如何确保下穿过程中施工本身及既有建(构)筑物的质量和安全,成为了当今地铁建设研究的一大课题.深圳市城市轨道交通6号线大雁山隧道在下穿西气东输燃气管道施工过程中,综合地采用了一系列的施工技术和方法,保证了施工过程的安全和质量,取得了良好的社会和经济效益,可为类似工程施工提供参考.
At present,with the rapid development of economy and society,numbers of subway construction are being carried out in cities.Underground engineering such as urban subway section often passes through existing buildings and municipal pipelines like gas pipelines.Metro construction requirements are in safety and civilization.How to ensure the quality and safety of the construction itself and existing buildings in under crossing process,has become a major topic in the study of Metro construction.During the construction of Dayanshan Tunnel in Shenzhen Urban Rail Transit Line 6 under passing through the gas pipeline of West-East Gas Transmission,a series of construction techniques and methods were adopted comprehensively,which ensured the safety and quality and achieved good results,providing valuable experience and suggestions for similar projects.
