Dam body drainage structure for high downstream water level of hectometer-level homogeneous earth dam
The invention discloses a high downstream water level dam body drainage structure of a hectometer homogeneous earth dam, which comprises drainage bodies arranged inside and downstream a dam body, and the drainage bodies comprise an arris drainage body, a horizontal drainage body and a vertical drainage body; the prism drainage body is arranged at the downstream of the homogeneous earth dam body; the vertical drainage body is arranged at the middle and lower reaches of the homogeneous earth dam body; the horizontal drainage body is arranged between the prism drainage body and the vertical drainage body and communicated with the vertical drainage body and the prism drainage body. The comprehensive drainage type formed by combining the vertical drainage body, the horizontal drainage body and the prismatic drainage body is adopted, the technical problem of dam body drainage when the hectometer-level homogeneous earth dam is higher than the downstream water level is solved, the dam body infiltration line is effectively reduced, the downstream dam slope stability is enhanced, meanwhile, the infiltration gradient of the infiltration line escape point is reduced, and the dam body drainage effect is improved. The dam seepage damage is avoided, and the seepage safety of the hundred-meter homogeneous earth dam body is ensured.
本发明公开了一种百米级均质土坝高下游水位的坝体排水结构，包括设置在坝体内部及下游的排水体，所述排水体包括：棱体排水体、水平排水体和竖向排水体；所述棱体排水体设置在均质土坝坝体下游；所述竖向排水体设置在均质土坝坝体中下游；所述水平排水体设置于所述棱体排水体与所述竖向排水体之间，并分别与所述竖向排水体和棱体排水体连通。本发明采用竖向排水体、水平排水体和棱体排水体三种排水体型式组合而成的综合排水型式，解决了百米级均质土坝高下游水位时坝体排水的技术问题，有效降低坝体浸润线，增强下游坝坡稳定性，同时减少浸润线出逸点的渗透比降，避免了大坝渗透破坏的的发生，确保了百米级均质土坝坝体渗流安全。
