[amp_mcq option1=”(i) and (ii),” option2=”(ii) and (iii)” option3=”(i) and (iv)” option4=”(iii) and (iv)” correct=”option1″]<\/p>\n
The correct answer is A. (i) and (ii).<\/p>\n
The main reinforcement in a counterfort retaining wall is provided on the bottom face in front counterfort and the inclined face in front counterfort. This is because these are the faces that are subjected to the maximum bending moment. The bottom face of the front counterfort is subjected to a bending moment due to the weight of the soil and the water pressure on the back of the wall. The inclined face of the front counterfort is subjected to a bending moment due to the weight of the soil and the water pressure on the front of the wall.<\/p>\n
The bottom face of the back counterfort is not subjected to a bending moment because it is supported by the soil behind the wall. The inclined face of the back counterfort is also not subjected to a bending moment because it is supported by the soil in front of the wall.<\/p>\n
Therefore, the main reinforcement is provided on the bottom face in front counterfort and the inclined face in front counterfort.<\/p>\n","protected":false},"excerpt":{"rendered":"
