In foundation design, while we do the base pressure check, we normally check if the attained pressure value is less than the GROSS BEARING CAPACITY of the soil which is the sum of net bearing capacity of soil and the overburden pressure. Actually, the overburden pressure acts against the net bearing capacity of the soil and I feel that we are actually increasing the bearing capacity value and doing the check. I feel that this is NOT right. Please clarify on this.
