Liquefaction resistance of soil with Liquiter

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,…

Rock masses and software

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…

CEDIMENTO DI UNA FONDAZIONE MISTA-Metodo PDR

Per effettuare il calcolo dei cedimenti di una fondazione mista occorre fare un’analisi di interazione per individuare come si ripartisce il carico trasmesso dalla sovrastruttura. Deve essere stimata la rigidezza di una fondazione mista che dipende dalla rigidezza della platea e dalla rigidezza del gruppo di pali, che a sua volta dipende dalla rigidezza del…

Slope stability analysis

Slope stability analysis: The term slope means a portion of the natural slope whose original profile has been modified by artificial interventions relevant with respect to stability. The term landslide refers to a situation of instability affecting natural slopes and involving large volumes of soil. Introduction to stability analysis The resolution of a stability problem requires…

Computation of settlements induced by the seismic action – Loadcap

Computation of settlements induced by the seismic action The computation of settlements induced by the seismic action is affected by significant uncertainties. The values that are obtained applying the procedures described below must be intended only as guidelines. The settlement is considered to be the lowering of the surface level, or, the integral of the…

Determination of geotechnical characteristic parameters

The article “Determination of geotechnical characteristic parameters” follows the base principles of the Eurocode. “The characteristic value of a geotechnical parameter shall be selected as a cautious estimate of the value affecting the occurrence of the limit state.” [EC7- 2.4.5.2 2(P)] Defining the geotechnical characteristic value means therefore to choose the geotechnical parameter that influences…

Projects with Sheet Pile Walls (SPW)

Sheet Pile Walls – Overview In order to have a more efficient usage of construction areas in congested urban areas a vertical development of buildings becomes necessary. Currently we more often face situations where urban buildings need as many parking spaces, so, due to lack of space, that requires the development of several underground floors.…
