Centrifuge Modeling and Numerical Simulation on the Deformation of Structure and Pipeline by Fault Slipping (Ii)

During fault slipping, the accompanying ground acceleration and ground deformation would cause the failure of structures. The seismic design of structure usually focuses on the ground acceleration. The deformation and ground surface deformation around the shear zone of fault leads to the damages of structure and the channels and pipelines for electric power, gas, water supply, internet and telecommunications. These would cause the multi-disasters and loss of lives and properties. This is a two-year project to study the soil structure interaction during fault slipping. The content of this study in first year, a hard soil deposit is prepared to study the effect of normal and reverse faults on the ground deformation and shear zone development by centrifuge modeling and numerical simulation. To continue the first year (2019) study, this project was proposed for two-year project. In 2020 and 2021 project, a pipeline system, a lower and higher structures are built on the ground surface. The interaction between structure, pipe line, affecting range of ground surface and movement of fault are studied. The behavior of structure movement and damage of pipeline would be used to improve the design of structures near the fault lines.
