Plate bearing test with 20 cm diameter plate on soil subgrade yielded a pressure of 1.25 x 105 N/m2 at 0.5 cm deflection. What is the elastic modulus of subgrade ?
56.18 x 105 N/m2
22.10 x 105 N/m2
44.25 x 105 N/m2
50.19 x 105 N/m2
None.

Deflection = (pressure x area of contact)/E.
0.005 = (1.25 x 10^5 x 0.1)/E.

E = none of the above.

E = (1.18Pa)/0.005.

Please explain the answer in detail.

Lakshmi said:   5 years ago
Es = (1.18XPa)/(0.5/100)
Es= 2.95X10power6N/sqm.
So answer is option E.

1.25*10^5/.5*1000 = 25*10^5.
