Artificial structures, such as buildings, bridges, tunnels, pipelines and dams, located on faulting zone may be destroyed by fault offset. However, some cases indicated that structures were not destroyed but only suffered from rigid-body displacement. The research is divided into three years, and the annual summary is as follows: In the first year, case study of faults propagate through composite soil layers are conducted to understand the deformation characteristics and failure processes. The research will be based on thrust faults, and sandbox experiment and numerical simulations (discrete element method, PFC3D) are used to figure out the deformation behavior of overburden soil. In the second year, the interaction behavior between the raft foundation of high-rise building and the diaphragm wall subjected to normal faults will be discussed. The three-dimensional coupling numerical analysis (PFC3D, FLAC3D) simulation is used to figure out the rigid-body displacement and the deformation of the raft foundation. By simulating and analyzing a case near Shanchiao Fault in Taipei, an appropriate planning and design method will be proposed. In the third year, the interaction behavior between the tunnel in overburden soil and fault which crosses the tunnel obliquely will be discussed. The three-dimensional coupling numerical analysis (PFC3D, FLAC3D) simulation is used to find out the mechanical behavior of the tunnel segments. The Shanchiao passes through the Tamsui–Xinyi metro line in Taipei will be studied. Analyze and forecast, and develop appropriate improvement methods.活動斷層複合地層變形砂箱試驗分離元素法（PFC3D）斷層與高樓基礎互制斷層與土壤隧道互制Active faultDeformation of Composite StrataSandbox experimentDiscrete element method (PFC3D)Interaction behavior between building foundation and faultingInteraction behavior between tunnel and faulting
