Title:
TEST DEVICE, SOIL MATERIAL CHARACTERIZATION METHOD, AND COMPACTION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2023005787
Kind Code:
A
Abstract:
To measure stiffness of soil material during a tamping test of the soil material.SOLUTION: A test device 10 is used for a tamping test of soil material (sample 11). The test device 10 comprises a container 12 capable of containing the soil material (sample 11) and having an open upper surface 12a, a weight 13 dropped onto the soil material (sample 11) housed in the container 12, an acceleration sensor 16 attached to the weight 13, and a stiffness measuring unit 20 that measures the stiffness (e.g., coefficient of deformation E) of the soil material (sample 11) in the container 12 based on the output from the acceleration sensor 16.SELECTED DRAWING: Figure 1
