Marine sediment is an important channel for methane leakage from the earth interior to atmosphere. The investigation of gas invasion in fine-grained marine sediments great theoretical and practical significance science engineering. To study mechanical mechanisms subjected shallow invasion, a injection test with self-developed experimental apparatus was performed, behavior investigated. results ...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...

The problem of a spherical cavity which is embedded in a linear, fluid-infiltrated, elastic porous medium and which is subjected to the sudden quasi-static application of a stress at the cavity boundary is solved. It is demonstrated that the deformation of the cavity is homogeneous regardless of the boundary condition imposed on the pore fluid at the cavity wall. For the case in which the pore ...
