Through simulation of unloading stress path of excavation works, a series of experiments have been down on stress path with the former state silty clay from a excavation project of yangtse tunnel engineering. This paper analyzes their stress-strain curve. Analysis shows that stress-strain curve and stress path have close relationship. Part of the final curve with a good characteristic, some not with hyperbolic curve characteristics and need further study.
