Application of Hilbert instantaneous spectrum on improved bolt anchoring quality detection

Engineering Reports, Volume 4, Issue 12, December 2022., 2022
A method utilizing a way to compute the instantaneous frequency curve of the bolt signal is proposed to overcome the phase folding problem existing in the Hilbert transform spectrum. The instantaneous frequency curve of the signal can help accurately identify the reflected signal from the bolt bottom and the position of the defect, thus accurately ...

On the seismic performance of straight integral abutment bridges: From advanced numerical modelling to a practice‐oriented analysis method

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 1, Page 164-182, January 2023., 2023
Abstract The seismic performance of integral abutment bridges (IABs) is affected by the interaction with the surrounding soil, and specifically by the development of interaction forces in the embankment‐abutment and soil‐piles systems. In principle, these effects could be evaluated by means of highly demanding numerical computations that, however, can ...

Formation and growth of multiple, distinct ice lenses in frost heave

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 1, Page 82-105, January 2023., 2023
Abstract This paper presents a fully coupled thermo‐hydro‐mechanical (THM) model which simulates frost heave in fully saturated soils. The model is able to simulate the formation and growth of multiple distinct ice lenses. The basic equations of the system were derived using the continuum theory of mixtures, nonequilibrium thermodynamics, and fracture ...

Two‐phase model for the excavation analysis in partially saturated soft soils using the particle finite element method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023
Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...
