Introduction: transportation and environmental sustainability
A brief history of transportation and the environment The relationship between transportation, technology and the environment is long standing. In the early 1920s, the car was first viewed as an improvement over the horse-polluted city environment. By the early 1930s, interest in an Interstate Highway System grew as a means to help get cars and trucks out of the mud. But, as automobile ownershi...
متن کاملOn preconditioning strategies for geotechnics
Iterative solvers are of increasing interest in geomechanics with the move towards 3D finite element modelling. Potentially, these methods can lead to reduced computational complexity as, unlike direct methods, they do not require the full system matrix to be assembled. In general, however, iterative solvers have not been widely adopted in geomechanics due to problems with convergence. This pap...
متن کاملGeneral report TC202: transport geotechnics
Today's needs of urban transportation including roads, railways, airports and harbours demand significant resources for infrastructure development in view of rapid and efficient public and commercial (freight) services. In most cases, authorities have had difficulties in meeting these service demands due to the rapidly growing public, industrial, mining and agricultural sectors in many parts of...
متن کاملGeomechanics and Geotechnics: From Micro to Macro
Granular anisotropy is attributable to many complex behaviors of granular materials and reflects important microstructures at the grain scale, and should be fully considered towards the development of realistic constitutive models for such materials. In this paper, we present a study on the behavior of anisotropy using a three-dimensional Discrete Element Method (DEM). Isotropic packings of san...
متن کاملApplication of Digital Photogrammetry in Geotechnics
Acquiring geometric data, such as coordinates, displacements or deformations, has always been a way to verify mathematical modelling in civil engineering. The introduction of finite elements methods further reinforced this trend. This paper reports on two applications of photogrammetry to soil and rock mechanics in order to provide an accurate and dense description of the deformation fields of ...
