泥岩地层条件下盾构下穿成昆铁路非预加固控制技术

Control Technology of Unprestressed Reinforcement of Chengdu-Kunming Railway Under Shield Driving in Mudstone Stratum

结合了成都地铁9号线盾构区间下穿成昆铁路的工程实例,结合现场掘进施工经验,并对盾构下穿铁路非预加固技术进行了充分的理论研究,有限元分析,并动态科学分析方法对盾构掘进参数进行了精准控制,最终实现了铁路安全穿越。

Is a combination of chengdu metro line 9 shield interval under wear ChengKun railway engineering example,combined with on-site construction experience,and in railway under the shield of the study of the theory of the pre-reinforcement technology fully,finite element analysis,and dynamic scientific analysis method for shield tunneling parameters for the precision control,finally realize the railway crossing safety.
