Vibration caused by shield tunneling construction have adverse impacts on surrounding environment. To ascertain the influence of ambient vibration, based tunnel project Zhijiang Road in Hangzhou, on-site vibration tests were carried out deep soil and surface during excavation, characteristics attenuation law investigated. The results show that main frequency near source is wide, response components can be observed at 0–100 Hz. Under filtering effect surface-covering layer, high-frequency are...
Metro Jet System (MJS) joint microdisturbance reinforcement is often adopted to strengthen and remediate existing tunnels that are severely deformed by under‐construction peripheral works, but analysis related the system of tunnel under consideration seismic effects insufficient at present. In this work, a field test MJS was conducted on basis subway deformation project. Then, numerical simulation study dynamic response performed in combination with wave direction intensity. Results show...
Dynamic load is an important factor affecting the safety and stability of subway tunnel structures. To obtain variation law shield structure dynamic response under aircraft taxiing load, a three‐dimensional numerical simulation such action performed on basis project involving orthogonal underpass taxiway. The effects sliding speed depth are also analyzed. results show that transverse displacement acceleration segment exhibit evident time‐space effect load. arch waist increase first then...
