In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 25 mm 20 mm 10 mm 15 mm TRUE ANSWER : ? YOUR ANSWER : ?
