Question

Which of the following is not the basis for the design of an arch dam?

(a) Thin cylinder theory

(b) Trial load theory

(c) Unit column theory

(d) Elastic theory

I got this question in homework.

This interesting question is from Arch Dams topic in section Arch and Buttress Dams of Irrigation Engineering

Answer 1

Right answer is (c) Unit column theory

Best explanation: Arch dams are designed on the basis of any one of the following three methods–

• Thin cylinder theory

• Theory of Elastic arches

• Trial load method

Out of these methods, the trial load method is generally adopted nowadays and it gives precise results.
