RCC Structures Design 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 20 mm 15 mm 25 mm 10 mm 20 mm 15 mm 25 mm 10 mm ANSWER DOWNLOAD EXAMIANS APP
