Reliability-based designs procedure of earth retaining walls in geotechnical engineering

The design and construction of foundations, retaining structures and slopes are usually based on deterministic formulations that do not allow the distinction between the natural variability and the inherent dispersion in the geotechnical parameters. Due to the inherent variability of the soil proper...

description	The design and construction of foundations, retaining structures and slopes are usually based on deterministic formulations that do not allow the distinction between the natural variability and the inherent dispersion in the geotechnical parameters. Due to the inherent variability of the soil properties, there is a growing trend to implement reliability-based designs in geotechnical engineering to reduce design uncertainties by probabilistic methods. The reliability designs require the definition of the probability density functions of the geotechnical properties, as well as knowledge of the spatial variability of soils. This paper identifies the procedures, type of soil investigations, simulations and the most commonly studied areas in geotechnical reliability-based designs. The importance of the correlation length in defining the reduction factors to determine the probabilities of occurrence of events, with Monte Carlo as the most used simulation method in this type of designs, is highlighted.
