EDH Soil Mechanics and Rock Mechanics Test Systems
●Rock mechanics Test System
It is essential for underground development to understand the failure
process of rock, which is subjected to tri-axial compression.This system has a tri-axial vessel loading high pressure, temperature
and high compression force, which is controlled by servo actuator.
EDH250-10 Rock mechanics Test System
Max. axis force
±1000kN
Max. side pressure
20MPa
Max. back pressure
20MPa
Max. axis displacement
±60mm
Side pressure displacement Volume
88cm3
Loading speed
0.01 to 4mm/min
●Permeability Test System
This system applies a tri-axial rock permeability test. It measures the
deformation of rock in three axes under the conditions of high temperature (up to 1200°C), high pressure (200MPa) and hot water,which are similar to deep underground.
An inert gas is used as a pressure medium.
EDH250-20 Permeability Test System
Max. pressure
200MPa
Side pressure displacement volume
126cm3
Max. volume variation velocity
3.14cm3/s
●Soil Mechanics Test System
This system is used for studies to analyze the soil mechanics
on the process of freezing and melting.
EDH202 Soil Mechanics Test System
Max. force
±200kN
Max. displacement
±50mm
Max. velocity
±30cm/s
Frequency range
0.1 to 20Hz
●Soil Mechanics Test System
This type is adapted to a wide range of tri-axial test ranged from soft
rock to sediment. The condition of tri-axial vessel is controlled by two
servo actuators, which give the test piece dynamical loading.
