Abstract
An in-situ dynamic settlement test bench and method for the foundation soil is provided. The in-situ dynamic settlement test bench includes a vibration table system, a sensor embedded in the foundation soil, and a water injection trench around the foundation soil. A horizontal vibration load is applied to the lower foundation soil at an in-situ testing site by means of a vibration table, and the dynamic response of the foundation soil is measured through the sensors embedded in different positions, to reflect the seismic settlement deformation of the soil body. Dynamic settlement tests on soils include indoor dynamic simple shear, triaxial and torsional shear tests. A method is proposed for measuring the dynamic response and settlement deformation of the foundation soil by using a vibrator's vibration action on an in-situ soil column. Measurements of the acceleration response and seismic settlement deformation are taken for the foundation soil under in-situ condition.
