The undrained remoulded shear strength of a clay, sur, is an important parameter in the design of a number of geotechnical applications. In the case of onshore tests the value of sur is generally obtained from vane tests. Recently, cyclic T-bar test...
View ArticleEntablatures, colonnades and “fault-joints” have been found in many excavations of dam foundations, tunnels and quarries in basaltic rocks of southern Brazil, but frequently they were not formally identified as such, and the two first, only rarely. This lack of recognition led many times to misunderstanding of their importance to slo...
View ArticleApplying Portland cement to soils is an excellent technique when it is necessary to improve local soil for the construction of stabilized pavement bases and to have a support layer for shallow foundations. Consoli et al. (2007, 2009, 2010) developed a rational dosage methodology for artificially cemented soils based on porosity/ceme...
View ArticleThe main purpose of this paper is to study the effect of annulus thickness on the quality of resin mixture for fully grouted resin bolt. Pullout and mixture tests were made in underground coal mines for the following arrangements: (a) 29 mm borehole diameter, and 19 mm roof bolt diameter with steel wire around the roof bolt; (b) 29 mm borehole diameter,...
