Abstract

The invention discloses a cementing rock-fill dam. The cementing rock-fill dam comprises a dam body and a seepage-proofing body. The dam body is of a ladder structure. The dam body is filled by cementing rock-fill materials. The seepage-proofing body adopts seepage-proofing body core walls or panels. The cementing rock-fill materials are dam construction materials formed by mixing rockfill materials with fine-grained soil screened out and cement or pouring mortar. The cementing rock-fill dam is filled by using the cementing rock-fill materials, the shear strength and elasticity modulus of dam body materials can be effectively improved, the dam body size and dam body non-uniform settlement are reduced, cracking of the seepage-proofing body can be effectively restrained, the cementing rock-fill materials can maintain the capacity that the rock-fill dam is adapted to deformation, the cementing rock-fill dam can be constructed on a flexible foundation and has a certain capacity of resisting overtopping flood so as to improve the safety of the dam, the construction technology is simple, the construction speed is high, and the project benefit is good; and the dam profile can be small, the project construction cost is low, and the adaptability to the ground foundation is higher, so that the cementing rock-fill dam can be built on topographies such as flexible dam bases and canyons.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a cemented rockfill dam. Background technique [0002] The related rockfill dam is a kind of dam with rockfill body as support and materials such as clay, concrete or asphalt concrete as anti-seepage body. Rockfill dams are widely used because of their strong adaptability to geological conditions, simple construction methods, good economic benefits, and superior seismic performance. However, when the dam height of the domestically built rockfill dam exceeds 150m, the rockfill body is prone to rheology and particle breakage under long-term high stress, and the dam body is prone to non-uniform settlement, resulting in cracks in the core wall or face panels. And the dam shape of the rockfill dam of the related art is compared with the cemented sand gravel dam and the rockfill concrete dam, and the dam body section size is big, is not suitable for canyon terrain, and t...
