DYNAMIC
PROBING
The Dynamic Probing test is used to determine the resistance of soils
in situ to the intermittent penetration of a cone, driven dynamically
in a standard manner.
The equipment consists of a 90° cone which may be sacrificial
or retained for recovery, a series of extension or driving rods,
a torque wrench and a driving device.
There are two type of test: Heavy Dynamic Probing (DPH) and
Super Heavy Dynamic Probing (DPSH). The dimensions of the cone
and the mass and drop height of the driving weight differ between the two tests. |
