The suction-control techniques commonly used for laboratory studies of mechanical behaviour of unsaturated soils are much more time consuming than standard soil mechanics tests. In addition, few laboratories have the required apparatus for testing unsaturated soils. This paper proposes an alternative method of analysing hydromechanical behaviour of unsa...
View ArticleThe frequent interruption of roads in some freeways in Brazil due to slope failure has caused economic losse sand potential harm to users. The paper presents data from a monitoring system installed at Serra do Mar in Santa Catarina State, Brazil. The slope monitored is called Morro do Boi and is located on BR-101 south, near the municipality of Itapema....
View ArticleThis paper illustrates the use of the seismic dilatometer (SDMT) to assess the decay of in-situ stiffness with strain level in different soil types. The approach adopted in this study relies on the ability of the SDMT to provide routinelyat each test depth both a small strain stiffness (G0...
View ArticleFor an appropriate stability analysis of pre-treated MSW landfill, the shear strength parameters of the material should be well defined in order to have a more realistic assessment of its geomechanical behaviour. As is well known, the shear strength of the material can be determined using two distinct components: friction (between the granular particles...
