WebSep 1, 2024 · The geotechnical parameters are estimated by back analysis referred to as monitored displacements and the model. In rock engineering, some parameters of the model are uncertain and are modeled as random variables X , characterized by their joint probability density function. Displacements of the host rock are monitored during … WebMar 3, 2024 · Performing back-analysis for geotechnical parameters is an expensive task as it requires many forward numerical simulations. Alternatively, developing a cost-effective surrogate model to be a function of geotechnical parameters (such as elastic modulus and Poisson’s ratio) and system response (displacement and stress) is more tractable.
