Application of integrated Game Theory-optimization subground stratification (-IGTOSS) model to Venetian Lagoon deposits

Abstract

The geographical and geological spatial variabilities raise challenges for geotechnicians to devise globally applicable subground stratification models working based on cone penetration testing (CPT). Recently, a novel CPT-based stratification and classification model was proposed in Tampere University, Finland. It combines the soil behavior type (SBT) classification chart proposed by Robertson (1990) with a novel integrated Game Theory-optimization subground stratification model (denoted herein as RIGTOSS). The model has already been verified based on few test sites results from Taiwan and the U.S. Therefore, in this paper, the RIGTOSS model is developed further, and it is evaluated based on the stratification profiles provided by CPT experts for the Venetian Lagoon deposits. The test site has been selected because of high variability of CPT measurements and the thin transient soil layers in the area. The results indicated comparable stratification profiles from the developed model(s) and the profiles by experts, derived based on field and laboratory tests.
