Resilient modulus is commonly used in prediction of long-term deformation performances pavement foundation layers under repeated traffic loads. For this reason, the determination material property accurately has a great importance designs. In study, resilient medium-dense sand-clay mixtures was investigated through cyclic triaxial and heart-shaped stress paths. purpose, specimens having clay co...

Initial shear stress is inevitable in actual engineering slopes, subgrades and foundations. The soils exhibit different dynamic characteristics under an initial stress. strength of saturated clay cyclic loading were studied through a triaxial test remoulded the Wenchuan area. effects failure criterion, vibration frequency on also analysed. results showed that strain criterion with value 2.5 % o...

to investigate the saturation induced collapse deformation behavior of rockfill material, a set of large-scale triaxial tests were conducted in saturated and dry-saturated conditions. specimens were tested under various confining pressures. for dry-saturated tests, specimens were sheared in various stress levels. results of all dry saturated tests indicate a sudden reduction in the specimen vol...

Geopolymer cement was evaluated as wellbore sealing material for carbon dioxide geosequestration application. Curing of cement system in saline water and strength testing in triaxial stress state condition under lateral confinement is relevant to primary cementing in CO2 geosequestration wellbore in saline aquifer. Geopolymer cement was cured in saline water (both at ambient conditions for 28 d...

Sand liquefaction triggered by earthquakes is a devastating geological disaster and has emerged as an engaging topic in earthquake engineering. With enhanced understanding of pure sand promoted laboratory research, there growing concern, following filed investigations, over the influence fine particles on potential containing inclusions. Efforts have been devoted to clarifying significance cert...

Taking the standard size coal block samples defined by ISRM as research objects, both properties of methane diffusion of coal block under triaxial compressive stress and characteristic influences caused by methane pressure were systematically studied with thermo-fluid-solid coupling with triaxial servocontrolled seepage equipment of methane-containing coal. The result shows the methane diffusio...
