点击翻译按钮获取中文摘要

To investigate the effect of tunneling on existing structure, model tests of tunneling are performed in deep underground considering existing building.From the model tests and numerical simulations it is found that for there is a significant effect of tunneling on the existing foundation of building even the tunnel is constructed in deep underground. Therefore, the effect of the soil-structure interaction should be taken into account during tunnel construction in deep underground. The numerical analyses perfectly capture the surface settlement, ground deformation and distributions of earth pressure of the model tests
