Question

The maximum safe bearing capacity of hard rocks with defects and lamination such as granite, diorite and trap is ___________ kN/m^2.

(a) 1650

(b) 3300

(c) 250

(d) 100

This question was addressed to me during an internship interview.

I'm obligated to ask this question of Ground Techniques in section Site Investigation and Ground Techniques of Construction & Building Materials

Answer 1

The correct answer is:

(b) 3300 kN/m²

The maximum safe bearing capacity of hard rocks with defects and lamination, such as granite, diorite, and trap, is generally around 3300 kN/m². This value is an approximation and can vary based on specific site conditions, including the degree of defects and lamination in the rock.
