Abstract
The hardening soil model has become one of the most widely used constitutive models in numerical analysis of excavations.The key issue of numerical analysis using hardening soil model is determining parameters of this model.Soil samples of typical soil layers(②2,③,④ and ⑤3) in Shanghai soft deposit is got by using thin wall samplers.The stress-strain curves of soil is got through triaxial consolidated drained test and triaxial loading-unloading-reloading drained test based on GDS and the load-strain curve of soil is got through consolidation test.Parameters of the hardening soil model are determined according to the test results.At the same time,relationships between,,and are established.The parameters and these relationships are also compared with those of soils in other districts.The test results can be used as references for numerical analysis of excavations in Shanghai and other soft soil districts.
