The presence of entrapped gas, formed by the degradation of organic matter, complicates the pore pressure measurement in gassy soils. To address this challenge, fully coupled hydro-mechanical finite element simulations are presented to analyse the pore pressure response observed from triaxial tests of gassy peat samples. The experiments incorporated novel local pore pressure transducers, able to track distinct pore pressure measurements at separate locations. By replicating the experimental tests, the numerical simulations assessed the effects of non-uniform gas concentration and soil-porous disk interactions to refine gassy soil testing procedures and improve data interpretation.

Abstract
The presence of entrapped gas, formed by the degradation of organic matter, complicates the pore pressure measurement in gassy soils. To address this challenge, fully coupled hydro-mechanical finite element simulations are presented to analyse the pore pressure response observed from triaxial tests of gassy peat samples. The experiments incorporated novel local pore pressure transducers, able to track distinct pore pressure measurements at separate locations. By replicating the experimental tests, the numerical simulations assessed the effects of non-uniform gas concentration and soil-porous disk interactions to refine gassy soil testing procedures and improve data interpretation.| File | Dimensione | Formato | |
