“…e simulation can be used for the geometry and the geological and geotechnical details of various construction materials. Researchers believe that numerical analysis must be carried out when the ratio σ cm /ρ 0 falls from the threshold of 0.15 [5]. e use of numerical simulation is not only effective for the systematic construction of tunnels but also useful for environmental protection.…”

“…Numerical simulation is one of the methods to examine such issues [9,10]. Moreover, numerical simulation is preferred by [5] to ascertain the interaction between the soil and rock, besides the tunnel structure. In order to deeply analyze the safety of the existing tunnel structure under the construction of the new tunnel, this research proposes a numerical simulation model.…”

Simulation is a powerful tool that can be used for systematic planning, analysis, and decision-making. Proper designing is preliminary required to construct a new tunnel over an existing tunnel to ensure safety and durability. Once an underpass tunnel completes, the interaction between the tunnel structure and the nearby soil gains a stable state and the stress of the tunnel is balanced. However, the stability of an existing tunnel is affected if the construction in the nearby area is not properly analyzed. This article proposes a numerical simulation model to empirically analyze lining force and surface settlement in order to ensure safety in engineering practice. The existing tunnel structure working condition is simulated under the new tunnel. The artificial honeybee colony algorithm is used to extract the parameter fusion characteristic value of tunnel influence and the model of estimating the bending moment of group piles. The structural mechanics of existing tunnels under new tunnels are analyzed using the triple bend model to improve the bearing capacity of existing tunnels under new tunnels. Based on the above analysis, numerical simulation experiments are designed. The proposed method has high accuracy and strong fitting ability and can effectively reduce the displacement of existing tunnels. Moreover, the method can improve the bearing capacity of tunnels. For tunneling operation, the results of the simulation may be used as a recommendation.
