Abstract:

The character of geomaterials is affected by stress path remarkably. Under different stress paths, the stressstraincharacteristics of geomaterials are difference. For the unloading path in existing engineering situation,the physical parameters and constitutive model is usually determined by loading test. The path to uninstall theactual project conditions which may be a larger error. Therefore, this work proceeding from the actual project,deep excavation of the lateral unloading condition is analysed. The tests of CTC path and RTC path on siltyclay in Huangshi city of china by multi-path tri-axial plane strain are carried on in the geotechnical EngineeringLaboratory of Huangshi Institute of Technology. Then, the phenomenon under the two stress paths arecompared with each other and describing the differences between them. The mechanical properties in the RTCstress path is analyzed mainly. Based on the Cam-Clay model framework, then derived this material yieldequation based on Cam-clay model, Laiding the foundation for the numerical analysis.

Keywords:

Silty Clay; RTC Stress Path; Plane Strain Test; Modified Cam-Clay Model
