VERTICAL LOAD TEST USING SAND BAGS - VEDA PILE FOUNDATION

The test can be initial or routine test. The load is applied in increments of 20% of the estimated safe load. Settlement is recorded for each 1hours and for each increment until the rate of settlement is less than 0.1 mm/hr. After reaching ultimate load, the load is released in decrements from the total load and recovery is measured until full rebound is established and next unload is done. After final unload the settlement is measured for 24 hrs to estimate full elastic recovery. Load settlement curve depends on the type of pile.
