Coolidge Dam was the first water storage facility ever constructed using a multiple dome design . Described simply, the design consists of two buttresses supporting three inclined eggshaped domes. The small end of the dome rests on the foundation, while the wider end, where the curve has a longer radius, is above. The domes are heavily reinforced with steel bars placed in the planes of the inclined arches from abutment to abutment. The buttresses are nearly triangular in shape. They are sixtyfeet thick at the base, twenty-four feet thick one hundred feet below the crest and sixty- two feet thick at the top. They are flared toward the upstream side of the dam to properly support the domes. The buttresses are reinforced with horizontal steel bars. There are two inclined contraction joints in the lower part of each buttress to prevent irregular cracks due to concrete shrinkage.
We think that design and construction of Coolidge Dam deserves a book length treatment. Consequently, we will only cover the basics here and provides links for further reading.
