This tester is used to determine the subsidence value of the roadbed under the static load, so as to evaluate the bearing capacity and deformation of the roadbed.
It is suitable for monitoring the quality of foundation construction of railways, highways, airports, urban transportation, ports, terminals and industrial and civil buildings subject to static loads.
After the ground is loaded and unloaded for the first time through the circular load bearing plate and the loading device, the second load is performed, and the measured stress σ of the load bearing plate and the corresponding center settlement value S of the load bearing plate are used to calculate The values of the deformation modulus Ev2 and Ev2 / Ev1.
