摘要
北京地铁六号线呼家楼站下穿京广桥、上穿既有地铁十号线,地下管线众多,安全风险极大。通过对该楼站暗挖段周边环境风险的充分调研,经过施工前的建模理论计算,确定了正常施工状态下的地层沉降对环境的影响,并据此,采取有针对性的综合施工技术措施,实现了高风险暗挖地铁环境风险的有效控制。
Beijing Metro Line 6,HuJiaLou station passes through JingGuang bridge and subway line 10,and there are numerous underground pipelines,which have great security risks.Through the full investigation of the environmental risks around the underground excavation section of the building,the influence of the formation settlement under normal construction conditions on the environment was determined through the modeling theory calculation before construction,and accordingly,the targeted comprehensive construction technology was adopted.The measures have achieved effective control of high-risk underground mining environmental risks.
