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
