Abstract

The invention discloses a grid type concrete faced rockfill dam. The grid type concrete faced rockfill dam comprises a wave wall, a dam crest road, a rockfill area, a transition layer, a toe board, a water-tight screen, reinforced concrete grids, a reinforced concrete face and a cushion layer, wherein the reinforced concrete grids comprise transverse grids and longitudinal grids; the transition layer is arranged on the upstream face of the rockfill area; the upstream face of the transition layer is provided with the transverse grids and the longitudinal grids which are crossed; multiple grid units are formed between the transverse grids and the longitudinal grids and are internally provided with the cushion layer; the cushion layer is provided with the reinforced concrete face; the toe board is arranged at the bottom end of the transition layer; the water-tight screen is arranged at the bottom of the toe board; the wave wall is arranged at the top end of the transition layer; the dam crest road is arranged on the top of the rockfill area. The grid type concrete faced rockfill dam has the advantages that the anti-seismic property is high, the reinforced concrete face is not prone to crushing failure and cracking failure, and a waterproof and water-tight system is high in safety degree.

Description

technical field [0001] The invention relates to a grid-type concrete face rockfill dam, which belongs to the technical field of rockfill dam engineering. Background technique [0002] Concrete face rockfill dam is an economical and applicable dam type. It can adapt to various terrain conditions and is easy to construct. The filling materials can be obtained locally, with less construction disturbance and fast progress. Among them, the concrete face slab as the main structure of the anti-seepage system of this dam type also has several advantages, such as short construction period, low cost and good performance. Therefore, this is also an important reason for the popularization of concrete face rockfill dams. [0003] However, the concrete panel also has its defects: the rockfill body behind the concrete panel will produce uneven settlement and horizontal displacement under the load of its own weight and the water pressure transmitted by the concrete panel, resulting in a par...
