Ground subsidence caused by tunneling is becoming a common problem in China due to rapid developing of underground space. Superstructures may crack and/or incline subjected to localized ground subsidence caused by tunneling. Ground subsidence would also induce breackage of buried pipelines which may even cause ground collapse due to pipe leakage. Mechanism of ground subsidence caused by tunneli…
Karst is a common geological condition in engineering construction. In order to study the influence of karst cave and boundary condition on the analysis of free field ground motion in karst area, viscoelastic artificial boundary was studied in free field ground motion analysis of karst region, a three-dimensional finite element model whose dimension is 1000 m × 1000 m × 500 m was set up, ch…
