Field Measurement and Numerical Simulation of Train‐Induced Vibration from a Metro Tunnel in Soft Deposits

open access: yesAdvances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Train‐induced vibration is increasingly attracting people’s concern nowadays. In the coastal areas, many metro tunnels are built in the soft deposits, so the train‐induced vibration effect is more serious. Nevertheless, the existing research studies mainly focus on the dynamic responses in the tunnel or on the ground surface while vibration ...

Dilatancy relation for overconsolidated clay [PDF]

open access: yes, 2017
A distinct feature of overconsolidated (OC) clays is that their dilatancy behavior is dependent on the degree of overconsolidation. Typically, a heavily OC clay shows volume expansion, whereas a lightly OC clay exhibits volume contraction when subjected ...

Application of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation [PDF]

open access: yesNumerical Methods in Civil Engineering, 2014
In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship.

The Constitutive Model of Rockfill Based on Property‐Dependent Plastic Potential Theory for Geomaterials

open access: yesAdvances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
To better control the strength and deformation of the roadbed, a constitutive model of rockfill was established based on property‐dependent plastic potential theory for geomaterials. The effect of the particle gradation on the anisotropy was described in the model.

A subloading surface clay and sand model [PDF]

open access: yes, 2023
The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading.
