Abstract:

In order to study the effect of traffic loading induced static deviator stress on the deformation of saturated soft clay, an undrained dynamic triaxial test is designed. The traffic loading is simplified as sine wave plus static deviator stress. And the rule of plastic deformation development is analyzed based on the examination data. The semilog plot of turning strain against failure vibration is presented and the influence of static deviator stress on it is studied. It is found that the bigger the static deviator stress is, the faster the deformation develops and the fewer cycles are needed to achieve the turning strain. The slopes curves of turning strain against failure vibration decrease and the intercepts are close when the static deviator stress incereases.

Key words: traffic loading, static deviator stress, undrained dynamic triaxial test, turning strain, failure vibration
