Triaxial Test Research on Dynamic Settlement of Ancient Architecture Foundation Soil Under Frequent Earthquakes

Abstract:

Owing to a long period of time in construction and using, coupled with the influence of earthquakes, most of the ancient buildings have a tilt and soils are in a state of non uniform stress distribution. By selecting different consolidation ratios and dynamic stress amplitudes, the dynamic triaxial test analogs two kinds of foundation soils, soft and hard, under uneven stress in small and frequent earthquakes to discuss the regulations between the parameters of soil and changes in stress level, and also provide references on stability assessment of ancient buildings in existing tilt. The results show the dynamic settlement of soft soil mainly occurs in the reconsolidation process after the vibration, while the hard one performs well under this circumstance and tends to be safer when its upper weights become larger.
