Study of mechanical properties of jointed rock mass using lattice-spring-based synthetic rock mass (LS-SRM) modeling approach
… of reliable estimates of strength and deformation properties of jointed rock masses. Three-dimensional lattice-spring-based synthetic rock mass (LS-SRM) models are generated by incorporating both planar and non-planar discontinuities to simulate the mechanical behaviors of both …

Ensaios triaxiais dinâmicos de um solo arenoso
… do Sul, in order to determine its resilient modulus. The procedures for setting up the testing equipment, calibrating and using it, are described. A compressed air system for applying axial loads and confining pressure, LVDT's transducers, and an oscillograph were used. Soil specimens were …

Numerical Validation and Refinement of Empirical Rock Mass Modulus Estimation
… engineering prediction of tunnel stability and deformation both during construction and post-excavation. The rock mass modulus of deformation is a necessary input parameter for many numerical analysis methods to describe the constitutive behavior of a rock mass. Tests for determining this …

Experimental and Numerical Study of Rubber Intermixed Ballast System Subjected to Monotonic and Cyclic Loading
… reduce dilation, control the degradation of the deformation modulus as well as reduce the breakage of natural rock aggregates. However, much higher rubber contents (>15%) may overly reduce the shear strength of the granular mix and also induce relatively large initial settlements. More …

Effect of grading and grain size on the friction characteristics of a sand/geotextile inteface
… procedure to approximate the constantly changing deformation modulus of the geotextile as it stretched in the respective sands, allowed the back-prediction of the pull-out force/displacement relationship, and thus enabled the study of skin friction distribution along the geotextile specimen during …

Assessment of shear modulus for granular soils, with small- to large-strain moduli correlations
Une estimation correcte du module de cisaillement (G) des sols constitue une partie fondamentale de l’analyse de la réponse dynamique des sols, des interactions sismiques sol- structure, et du potentiel de liquéfaction du sol. Le module de cisaillement à petites déformations (Go) peut être …
