| Abstract: | 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. |
