The Stability Evaluation of the Underground Cavern Group under the High-Rise Building

摘要：

In this paper, the effect of the high-rise building on the bomb shelter group is studied through the 3D numerical simulation. The stress and displacement states of the tunnel at each loading stage are calculated. By analyzing the stress and displacement of the tunnel, we found that the distributions of the stress and displacement are relative to the magnitude of building load, the position relationship between the cavern group and the upper building, and the structure of the cavern group. Based on the stability criterion of the cavern group, the stability of the tunnel is checked, and accordingly, the reasonable reinforcement measure is proposed.
