The number of blows required to drive the penetrometer into the ground through a distance of 300 mm is measured which is known as _____________ of the soil.(a) Standard penetration resistance(b) Bearing power of soil(c) Maximum safe bearing capacity(d) Allowable bearing pressureI got this question during an online interview.My doubt stems from Site Exploration Methods topic in section Site Investigation and Ground Techniques of Construction & Building Materials

Answer»

Right ANSWER is (a) Standard penetration RESISTANCE

Easiest explanation: The bearing capacity and the other engineering properties of certain TYPES of soil are they KNOWN by referring to the curves correlating Standard Penetration Resistance or SPT and the CORRESPONDING characteristics of soil. The values of SPT of soil and different depths are determined.
