plz solve this probload test conducted at depth 1m below gl witha square plate of 30cm on a granular soil load req to cause 25mm settlement was 7.2tonnes if the settlement is limited to 10mm the allowable bearing pressure will be?ans:32t/m^2

Use direct IS code method..for any other given settlement value net allowable bearing pressure can be estimated by assuming that the settlement varies with the soil pressure in direct proportion. (Page 522, soil mechanics and foundation engineering, S K Garg)so net bearing pressure for 25 mm settlement= 7.2/ (0.3*0.3) =80 t/m^2net allowable bearing pressure for 10 mm settlement= (10/25)* 80 = 32 t/ m^2
