| Research Abstract |
For the development of urban areas several types of underground structures are constructed by means of tunneling. However, tunnel excavations inevitably cause ground deformations and may affect existing structures near the tunnel. Therefore, it is required to provide reliable forecasts of the inevitable settlement associated with the tunnel excavation. In tunnel design usually the influence of excavation patterns and the interaction effect of ground and existing structure are not taken into account. This research provides a guideline to deal with the soil-structure interaction effect in using underground space, which is a common problem in urban area. In many cities some of the tunnels are located less than 1m gap in some sections and some are parallel to others. In this research the effect of adjacent tunnels has been investigated with laboratory model tests and numerical simulations.
