Hoover Dam Construction

The best way to view the pictures is to use the links below.

It isn’t easy to record the enormous size of the construction of the Hoover Dam in pictures. Today I will try to give you a proper impression in 5 pictures.

◙ The main picture shows a horizontal panorama of the concrete construction of the dam. You can clearly see the junctions made by the parts of the formwork during the fabrication.

◙ The first workshop gives an impression of the dam looking from the middle of the dam downwards to the power station.

◙ The second workshop is a triptych of three pictures looking downwards to the power station.

The Hoover dam is a combination of two type of dam construction. An arch dam and a gravity dam combining the best features of both.

An arch dam is a concrete dam that's curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, compressing and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow gorges or canyons with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas

A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by primarily utilising the weight of the material alone to resist the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable, independent of any other dam section.

I add the dark frame to the picture to give the posts a screen format of 1920x1080 pixels
The idea is that, if you use the links in the text, you have a full screen image of the picture with the photo in the centre of a dark screen.
This works with the browsers and screens I use, but I’m not sure that everybody will have the same result.
