| 摘要 |
The aim of this invention is to provide methods and devices for in-situ measure of ground heave characteristics. The sensor or device of the invention comprises at least two independently inflatable elements, one of which (111) allows for standard and traditional measurements of ground pressure in its original state, the other (112) being combined with fluid injection means (10) which allow for ground heave pressure measurements simultaneously with the impregnation of the ground until saturation, either at a constant pressure, or a constant volume.
