The great structures

This publication is dedicated to the Great constructions of the USSR and Russia, those buildings are one of its existences prove the power and might of our own country want to meet. THE GREAT STRUCTURES

At the bottom of each building is a link to all the pictures in the archive!

Well it because we all live in Primorye we should all know about Voroshilov Battery on Russky island that is why she is entrusted with a great honor to open a Hit Parade of GREAT FACILITIES

There is no doubt that the Egyptian pyramids is the most famous. But they are not the most ancient structures of pyramidal form. In the U.S. state of Wisconsin there is a pyramid, whose age, presumably, 12 thousand years. It turns out that it was built during the last ice age. And made it a very highly advanced civilization…

Rock lake is located 20 miles East of Madison (Wisconsin). Its length is eight and the width is about four kilometers. In 1836, American Explorer Nathaniel, hair accidentally discovered in the lake a small stone pyramid with a flat top. He called his discovery Atzalyno and suggested that the discovery not less than a thousand years.

It was argued that the pyramid is on the bottom of the lake which was formed many years ago, and, therefore, the construction should be over all Indian tribes. Continue reading

The soil pressure on underground structures

Prior to production and to the construction of underground structures soil in an unlimited array is in a state of natural or geostatic equilibrium under the action of its own weight. In this case, the depth Z in the soil (Fig. 1), the following compressive stresses (pressure):

vertical

horizontal

where is the average bulk weight of overlying soils; – the coefficient of lateral earth pressure under conditions of natural occurrence.

The open or underground excavation changes the equilibrium conditions of the soil and leads to the emergence of deformation and redistribution of stresses.

Earth pressure on underground structures is different than the pressure in the intact rock mass at the same depth, as: Continue reading
