Numerical analysis of seismic performance of deep strutted excavation-structure interaction in sandy soil
This research investigates numerically the seismic performance of deep-braced excavation in adjacent to 10-stories building in sandy soil. Non-linear time-history analysis using hardening soil model with small strain stiffness (HS-small) is performed using PLAXIS 2D. Numerical validation of a real case study of deep-br...

Numerical Investigation of Seismic Responses of Fault-Crossing Segmental Water Conveyance Tunnel
Tunnels are important infrastructures, but faults and internal water pressure can reduce their seismic performance. These risks are relevant in seismic regions including Indonesia. Although finite element methods are used to analyze tunnel behavior, models with continuous linings overestimate stresses, while the influe...

Shaking table modelling on seismic response and failure mechanism of submerged silty clay slopes
Abstract Earthquake-induced submarine landslides threaten marine infrastructure, yet their destabilization mechanisms remain poorly understood. This study utilizes a large-scale 1 g underwater shaking table test with intact marine silty clay to investigate the dynamic response of submarine slopes under multi-stage seis...

Coupled hydromechanical responses around a roadway excavation in inclined coal–mudstone strata
We conduct a numerical investigation into the spatio-temporal evolution of excavation-induced disturbances around roadways in inclined coal–mudstone strata containing fracture networks. The intact rock is modeled using a Mohr–Coulomb plastic constitutive law to capture deformation and failure, while the displacement of...

Seismic Performance and Strength Prediction of Precast RC Shear Walls with Openings for Cavity Structures Crossing Underground Utility Tunnels
Additional loads from new buildings spanning existing underground utility tunnels, together with seismic action, may induce uneven settlement and structural damage in tunnel systems. To mitigate this risk, a precast cavity structure is proposed to replace the soil above the tunnel, isolating load transfer and controlli...

Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau
Currently, tunnels are key infrastructure projects for traversing the Loess Plateau and ensuring rail connectivity. However, seismic damage surveys indicate that tunnels built along mountainsides in the Loess region suffer severe damage during earthquakes due to their low structural damping and inadequate seismic per...
