The Problem of Filtration around Seeprings of Bottom Culverts in Earth Dams (Zagadnienie Filtracji Wokol Pierscieni NA Dennych Upustach Zapor Ziemnych)
The design of earth dams involves the construction of special hydraulic structures serving for the discharge of water. They are spillways and culverts. The size and construction of spillways varies from type to type, depending on the amount of water that has to be passed through the dam and on the water head in the reservoir. In the case of an inconsiderable water head and flow rate, a steel pipe provided with a closing flap at the inlet is laid under the dam structure. With appreciable water-flow rates, culverts from joined concrete or reinforced-concrete elements with a cross section suited to the amount of discharged water are made. A closing arrangement of a design depending on the water head in the reservoir is installed at the culverts inlet, and in this case the conduit operates on the principle of pressure-free pipes. Outlet works should be carefully built so that the occurrence on joints of any untight spots or fissures causing water leakages from the conduit during its operation or the entry of dam material when the conduit is empty may be avoided. The most advantageous solution would be to locate the conduit on solid ground, since displacements of the dam or the culverts caused by the settling of the foundation may give rise to breaks in the culverts or fissuring in the dam body in the former's vicinity.
