Problems solved by technology

However, it is difficult to deal with the problem of seepage safety under the condition of large deformation caused by high seismic force, and once seepage damage occurs, it is very likely to cause dam failure and cause serious harm. This is also an important reason restricting the construction of earth-rock dams in areas with high seismic intensity.

Embodiment Construction

[0034] This embodiment is a clay core dam with anti-seepage and self-healing function. The clay core dam body has a clay core 12, and the upstream side of the clay core 12 is sequentially provided with a self-healing silt area 11, an upstream filter Zone I10, upstream filter zone II9, upstream transition zone 8, and upstream rockfill zone 7, downstream of the clay core wall 12, downstream filter zone I13, downstream filter zone II14, downstream transition zone 15, and downstream rockfill zone 16.

[0035] The dam foundation of the clay core dam in this embodiment is divided into the core wall foundation located in the middle area and the dam rockfill foundation located upstream and downstream of the core wall foundation. The rockfill foundation of the dam body is rock foundation or dense soil with no risk of earthquake liquefaction foundation; the foundation structure of the core wall has a concrete bottom plate 5, and the rock foundation under the concrete bottom plate 5 is c...

Abstract

The invention relates to a clay core wall dam with anti-permeation and self-healing functions and an implementation method of the clay core wall dam. The aim is to provide the clay core wall dam withthe anti-permeation and self-healing functions and the implementation method of the clay core wall dam, so that the dam guarantee that the permeation quantity and permeation stability are in controllable and safe states under the condition of large deformation caused by high earthquake force. According to the technical scheme, a clay core wall is arranged in the clay core wall dam with the anti-permeation and self-healing functions, and the clay core wall dam is characterized in that a self-healing floury soil area is arranged on the upstream side of the clay core wall; and when stretching ordislocation slits happen to the clay core wall, floury soil in the self-healing floury soil area can flow to fill in slits of the clay core wall. The clay core wall dam is suitable for earth and rockfill dam projects built in high-seismic-intensity regions.

Description

technical field [0001] The invention relates to a clay core dam with anti-seepage and self-healing functions and an implementation method thereof, which are suitable for earth-rock dam projects built in areas with high seismic intensity. Background technique [0002] An important reason restricting the construction of reservoirs in high seismic intensity areas is the seismic safety of dams. The seismic safety of earth-rock dams mainly includes dam structural stability and seepage stability. Among them, there are many ways to deal with dam structural stability, and the technical more mature. However, it is difficult to deal with the problem of seepage safety under the condition of large deformation caused by high seismic force, and once seepage damage occurs, it is very likely to cause dam failure and cause serious harm. This is also an important reason restricting the construction of earth-rock dams in high seismic intensity areas. Contents of the invention [0003] The t...
