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…
In recent years, because of the controlled blasting engineering in China concentrated in the downtown area, the surrounding environment of the downtown area is complex and the underground pipeline is dense, which poses a great challenge to the controlled blasting. It is of great significance to study the impact of falling ground vibration caused by controlled blasting on the underground stati…
As an important part of critical infrastructure, shield tunnel is widely used in urban area of China recent years. The safety of shield tunnel during construction and operation has drawn more and more attention. In the operational period, real time deformation monitoring is an effective way to help us to reveal the long-term deformation mechanism and control the lifetime safety of shield tunn…
The filter cake on the tunnel face has a significant influence on project of the slurry-driven shield. During the excavation, only permeable filter cake is allowed to form because the rotating speed of cutter wheel is fast. Through the filter cake, the water of slurry will infiltrate into the soil. The water enhances the hydraulic head and the risk the failure of tunnel face. In order to determ…
