Q:

Which of the following dam is also known as the Amberson dam?

A) Multiple arch buttress dam B) Mushroom head buttress dam
C) Massive head buttress dam D) Free deck buttress dam
 
Answer & Explanation Answer: D) Free deck buttress dam

Explanation: Free deck slab type dam is generally preferred for smaller heights. Rodriguez dam in Mexico is the highest dam of such kind having a height of 73.2 m. They are virtually referred to as Amberson dams.

Q:

Which of the following dam requires no reinforcement?

A) Fixed deck buttress dam B) Simple deck buttress dam
C) Cantilever deck buttress dam D) Massive head buttress dam
 
Answer & Explanation Answer: D) Massive head buttress dam

Explanation: Massive head buttress dam does not use slabs or arches for the upstream face. The head of the buttresses are enlarged to meet each other to form a continuous water supporting surface. The bending, as well as diagonal tension in the upstream part of the dam, is absent, so the deck is not reinforced.

Q:

Multiple arch dams are generally used for ______________

A) high heights B) low heights
C) medium heights D) any height
 
Answer & Explanation Answer: A) high heights

Explanation: Free slab type dams are generally preferred for smaller heights and multiple arch dams are used for higher dam heights. Manicougan-5 dam in Canada is the highest multiple arch dam of the world having a height of 210 m.

Q:

The load from the deck of a buttress dam is transmitted to the foundations through the ______

A) corbels B) buttresses
C) lateral braces D) sloping deck
 
Answer & Explanation Answer: B) buttresses

Explanation: Buttresses are solid walls of specified thickness and sections are constructed parallel to the flow at suitable intervals. They are used to support the vertical slab which holds the water. The stability of the dam against external forces is obtained by transferring the water pressure to the supporting buttresses.

Q:

The best design of an arch dam is when __________________

A) all horizontal water loads are transferred horizontally to the abutments B) the dam is safe against sliding at various levels
C) the load is divided between the arches and cantilevers and the deflections at the conjugal points being equal D) the deflections of the cantilevers are equal at different points
 
Answer & Explanation Answer: C) the load is divided between the arches and cantilevers and the deflections at the conjugal points being equal

Explanation: In the trial load method, deflections for the arches are calculated at the points where the cantilevers cross it in each trial. If the deflection calculated at these points from cantilever elements is within reasonable limits and same, then the assumed distribution of load is correct. If not, then the calculations are repeated using a different set of load distribution until the condition is satisfied.

Q:

According to thin cylinder theory, the volume of concrete required for an arch dam would be minimum if the central angle is ____________

A) 130° 34’ B) 133° 34’
C) 143° 34’ D) 153° 34’
 
Answer & Explanation Answer: B) 133° 34’

Explanation: The most economical central angle is equal to 133°-34’ and such an angle can be adopted only at one place in constant radius arch dam as there is considerable variation with height due to narrow V-shape of the valley. It is therefore considered to keep the economical angle of 133°-34’ at about mid-height for a minimum value of concrete.

Q:

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
 
Answer & Explanation Answer: C) Unit column theory

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.
