摘要
依托重庆地铁6号线一期工程,应用有限元分析软件进行数值模拟计算,计算了不同围岩级别、不同近接方式、不同双洞净距情况下的围岩应力变化值,以此为依据划定不同的影响范围,分析了影响范围的发展趋势,为类似工程实例提供借鉴和参考依据.
The sixth Chongqing metro line is taken for example, and the numerical simulation is applied for finite analysis and calculation. The change of stress value is obtained at different level of surrounding rock, different connecting modes and different double hole net distance, then the different influence scope is delimited and the development trend of the influence scope is forecasted, thus to provide the reference and basis for the similar case.
