摘要
城市轨道工程具有特殊的建设环境特点,如何在安全、优质、高效地推进新线建设的同时,确保线路沿线周边环境及既有设施的安全是必须妥善解决的问题。针对北京在建地铁45、、10号线的工程环境风险源情况,论述了针对不同的环境风险源如下穿既有结构、邻近既有建筑以及在既有桥梁等市政设施区域施工地铁工程等确保环境安全所采取的合理的、有效的处置方案。并通过列举工程实例,验证了方案的合理性及效果。
Urban tuunel engineering is characterized by special construction environment. How to advance the construction process with safe, effectiveness and high-quality is an inevitable problem to deal with properly so as to ensure the safety on environment and existing facilities around the tunnel lines. Based on the engineering risk sources from Beijing metro lines No. 4, No. 5 and No. 10, the paper presents some rational and effective measurements and disposal schemes. These concepts include urban tunneling trader-crossing and closing to existing buildings, bridges and other municipal facilities. Construction results show the rationality and effect of the scheme.
