Plate Bearing Test

PLATE BEARING TEST

Plate Bearing Test is test procedure for evaluation of Bearing Capacity of soil under field loading condition for a specific loading plate and depth of embedment. In this method of testing, consist of applying direct load of known magnitude through hydraulic jack, on to the steel plate and measuring its corresponding vertical displacements.  This test method can be used as part of a procedure for soil investigation for foundation design.

Procedure for Plate Bearing Test will follow Cyclic Loading Schedule from ASTM D1194.

The sequences of the plate load test will be presented in the following procedure:

                                    i.         Set the initial elevation of the reference plate (300x300mm) from the nearby benchmark point.

                                  ii.         Record the initial dial gauge reading with no pressure of hydraulic jack, record the time.

                                 iii.         Apply the pressure via hand pump to increase loading weight, record the dial reading at every designated (see our attached schedule table).

                                iv.         Settlement of plate reading by 4 dial gauge there are placed and fixed into the magnet base at above the leveled artless glass.

                                  v.         Settlement Reading :

-       Reading is conducted every 3 minutes

-       In the maximum load (8.5 tons) reading is conducted in every 3 minute of interval for first 15 minutes.

-       For details reading in every loading step can be seen in the Loading Schedule.

                                vi.         Record the current elevation of reference beams for each of starting loading cycle (see our attached schedule table).
