In Penetration test, the formula obtained for the safe bearing capacity of soil per unit area is given by?(a) R÷{A×F}(b) R-{A×F}(c) R+{A×F}(d) R×{A×F}The question was asked in exam.I'd like to ask this question from Ground Techniques topic in section Site Investigation and Ground Techniques of Construction & Building Materials

Answer»

The correct choice is (a) R÷{A×F}

Best explanation: Safe bearing CAPACITY of soil per unit area = R÷{A×F} where R is EQUALS to ultimate resistance of soil, A = 2 CROSS sectional area of the substance, F equals two FACTOR of SAFETY. The results obtained by this method are approximate and hence this method is used for minor engineering structures.
