Device for determining the stress-deformation behavior and / or deformation modules and / or strength properties at different depths, in particular of loose rocks and of landfill bodies in situ.

摘要

The system uses a loading plate to determine soil strength parameters e.g. stress-deformation relationships and strength characteristics of loose stones, landfill bodies, etc. The load plate measures the pressure and pore water pressure at different depths under load or displacement control. The load plate has a screw loading body and pore water pressure is determined with a measuring instrument under the body. Vertical pressure is measured with a measuring instrument in the upper shaft of the load plate. A measuring instrument is located on the site surface for deformation measurement. Samples can be taken and waste gas can be tapped off.
