Dam slope wave release column array

SHEN ANYANG / CAO PU

A wave release column array for a dam side slope belongs to the technical field of wave resistance of coast and river banks and comprises a plurality of wave release columns which are arranged on the dam side slope in a staggered manner to form the wave release column array. The wave releasing column is a reinforced concrete column and is a butterfly-shaped column body with a butterfly-shaped cross section, and the butterfly-shaped cross section is formed by connecting two symmetrical front curves and two symmetrical rear curves; a curved surface formed by the two front curves on the wave releasing column is a front flow releasing surface, and a curved surface formed by the two rear curves on the wave releasing column is a rear backflow surface; the wave releasing column has the advantages that the wave releasing column can distribute directly-impacted sea waves to the two sides, and the direct-impacting sea waves on the two sides are slightly blocked through the distributed sea waves with the impact direction changed, so that the impact force of the sea waves is relieved; the wave releasing column arrays formed by the wave releasing columns can enable sea waves to pass through the wave releasing column arrays arranged in a staggered mode, and the overall impact force of the sea waves is effectively relieved.

一种堤坝边坡泄浪柱阵，属于海岸河岸防浪技术领域，其包括泄浪柱，若干个泄浪柱错位排列在堤坝边坡上构成泄浪柱阵；所述泄浪柱为钢筋混凝土柱，是横截面为蝶形的蝶形柱体，该蝶形横截面由呈对称状的两条前曲线和呈对称状的两条后曲线连接构成；其两条前曲线在泄浪柱上构成的曲面为泄流前表面，两条后曲线在泄浪柱上构成的曲面为回流后表面；其有益效果是泄浪柱可将直接冲击过来的海浪分流向两侧，并利用改变冲击方向的分流海浪略微阻挡两侧直冲的海浪，从而减缓海浪的冲击力；由泄浪柱构成的泄浪柱阵可使海浪在错位排列的泄浪柱阵中穿行，有效减缓海浪的总体冲击力。
