Contribution to applications of back analysis methods in geotechnical engineering

Abstract

Rapid progress in technology concerning computer programming affected civil engineering as well as other sciences. In the field of geotechnical engineering advanced soil models started to appear and have replaced the elastic and the elastoplastic Mohr-Coulomb soil model. These advanced models have better results when are used in finite element method. Though, it.s already known that uncertainties in advanced soil parameters input values are reducing solving accuracy. An alternative method that resolves values of unknown soil parameters is back analysis. This kind of analysis follows inverse course comparing to classic predefined analysis. So, by using field measurements as input data in back analysis procedure we are able to calculate with good accuracy soil parameters. Although the idea of back analysis exists since 1969 when Peck defined it, there is no standard, general and accepted method of back analysis. Most of them refer to the elastic problem with limited use in certain kind o ...
