アブストラクト
Cement treated soil is characterized by the brittle property that shows high compression strength and small strain at failure and low tensile strength. A series of centrifuge model tests was conducted to investigate the failure pattern and stability of cement treated clay ground having an unsupported vertical slope. The model ground was subjected to monotonically increasing centrifugal acceleration until it failed due to the enhanced self-weight. It was found from the test results that the model ground failed with a combination of a vertical tensile crack and a straight shear failure plane, which was much different from the failure phenomenon of sandy or clayey ground. It was also found that the conventional pseudo-static limit equilibrium method was not able to evaluate the critical height and the failure zone of the model ground accurately. The test results were compared with the numerical analyses in which the treated soil was simulated by the expand SPH method.
