Free gas in sandy marine sediments is a common occurrence worldwide. A distinct feature of gassy sand that, under undrained shearing, presence occluded bubbles the pore fluid can increase strength at relatively loose state, while reduce dense sand. Previous theoretical analyses have primarily focused on modelling ‘beneficial’ effect free migrating static liquefaction, with few attempts to descr...

Young coastal fens are rare ecosystems in the first stages of peatland succession. Their drainage compromises their successional development toward future carbon (C) reservoirs. We present the first study on the success of hydrological restoration of young fens. We carried out vegetation surveys at six young fens that represent undrained, drained, and restored management categories in the Finni...

The undrained shear strength of clay is an important parameter for the design embankments, shallow foundations, and pile foundations. Among various methods testing strength, simple essential when shearing mode soil surrounding similar to that in a test. This study employs series tests with Berkeley apparatus. Three reconstituted natural clays one artificial were tested range coefficients consol...

As the main reservoir of oil and gas resources, physical mechanical properties rock are complicated. The strong heterogeneity flow in porous media further influences nature stress propagation. Therefore, considering heterogeneous particle model fluid-structure coupling, it is very important to study variation law under a state, which lays foundation for formation fracturing mining. In this pape...
