Probabilistic Analysis on Excavation Responses
The soil parameters used for analysis by numerical methods are not necessarily the “true” values of these parameters, since such data obtained are estimated based on limited field tests, laboratory data, or local experience, generally involving considerable uncertainty. In addition, the wall and ground responses in a supported excavation may also be influenced by construction quality/workmanship and other environmental factors. Thus, deterministic modeling using numerical methods such as the finite-element or finite-difference method, even with advanced soil constitutive models, may not be able to take into account all the uncertainties and complexities mentioned above. To this end, the probabilistic framework combining a simplified wall deflection estimation model with reliability methods that are able to take into account the soil parameter uncertainties is desirable.
