摘　　要：以某城际铁路江面冒浆事件为例,分析江面冒浆及刀盘抱死原因并研究相关处置技术措施。通过现场实践可知,采取的相关技术措施可靠有效,且周边建筑物安全稳定,并可快速完成处置恢复掘进,可为类似盾构穿越江河施工提供借鉴。Taking an inter-city railway river slurry incident as an example,the causes of river slurry and cutter head lock were analyzed and the relevant technical measures were studied.The on-site practice shows that the relevant technical measures taken are reliable and effective,and the surrounding buildings are safe and stable,and the disposal and restoration excavation can be quickly completed,which can provide reference for similar shield crossing river construction.
