摘要

The Plavinas hydroelectric power plant, which forms the third stage downstream in the cascade of hydro units on the Daugava River (Latvia), was constructed in 1962-66 under a plan developed by the Russian "Gidroproekt" Institute. The configuration of the hydro unit with a 40-m head includes (Fig. 1) a spillway hydroelectric plant with a headwall length of 200 m, a riverbed earthfill dam with a length of 480 m, a left-abutment earthfill dike extending 2 km into the Daugava watershed and its tributary the Lautse River, a right-abutment earthfill dam (approximately 450 m) and its 1-km continuation, a low-head dike. To lower the heads and prevent seepage soil deformations in the foundation of the building structures, the plan calls for various drainage constructions.
