摘要

Estimating building damage due to ground movements induced by tunneling or open cutting is very important for planning, design, and construction. Such efforts can minimize any possible damage in adjacent structures and help in choosing the most efficient protection measures if needed. This study extends a damage estimation criterion based on the 2D state of strain (Son and Cording, 2005) to estimate building damage and distortion in 3D structural distortion conditions. The 3D state-of-strain concept is used to develop a damage criterion that can be used to estimate building damage and distortion in 3D distorting structural units. The extended 3D criterion is compared with observed field observations as well as numerical test results. The study results can provide a better understanding of building damage estimation in 3D structural distortion conditions in response to tunnel and underground excavation-induced ground movements.
