The soil reaction coefficient, or Winkler coefficient, is normally referred to as K or KS [kgf/cmc]. In Winkler’s model, the subsurface is characterized by a linear relationship between the failure of a point (s) and the contact pressure (p) at the same point: p = K s K is the “background constant” or “coefficient of…

Liquefaction resistance of soil with Liquiter … Simplified procedure for evaluating liquefaction resistance of soils Following disastrous earthquakes that occurred in Alaska and Niigata (Japan in 1964), Seed and Idris (1971) proposed a simplified methodology for assessing the resistance to liquefaction of soils. This methodology has been selected and improved over the years (e.g. Seed,…

In the technical field it is important to document the works through photographic reports and geo-locate them on the map. The technology we have today allows you to easily get your position in real time. With few economic resources can get smartphones, tablets and PCs, equipped with GPS. Of course in the case of investigations…

Rock masses and software For the rock masses complex formations, geotechnical characterization and modeling is necessary to evaluate the characteristic resistance: the nature, geometry and resistance of discontinuities are important. In addition, it must be specified whether the characteristic resistance refers to discontinuities or to the rock mass. In this respect, we want to give…
