GTJ-Ev2 static deformation modulus tester
Usage overview
The GTJ-Ev2 static deformation modulus tester is used to determine
the subsidence value of the subgrade under static load, thereby
evaluating the bearing capacity and deformation of the subgrade. It
is suitable for monitoring and monitoring the quality of foundation
construction of railways, highways, airports, urban transportation,
ports, terminals and industrial and civil buildings under static
load.
After the first loading and unloading of the ground by the circular
carrier plate and the loading device, the second loading is
performed, and the measured stress σ of the carrier plate and the
corresponding center settlement value S of the carrier plate are
calculated. The values of the deformation moduli Ev2 and Ev2/Ev1.
Applicable standard
Railway Engineering Geotechnical Test Procedures (TB10202-2010)
Features
※ Imported sensors and some components are used for high test
accuracy.
