Trapezoidal-block embankment structure

The invention discloses a trapezoidal-block embankment structure and relates to an embankment structure of embankment engineering. In the technical scheme, the embankment structure is formed by arranging trapezoidal blocks with a complete block in the cross-section direction on a foundation bed and carrying out longitudinal and continuous arrangement and connection on the blocks gradually; each trapezoidal block is a block body with the cross-section direction being similar to trapezoid and the whole body being similar to a trapezoidal prism; the included angles between the slope surfaces of the two horizontal sides of each trapezoidal block and the horizontal plane are not larger than 60 degrees, and are larger than or equal to 18 degrees and smaller than or equal to 45 degrees when waves are larger; the height of straight walls at the two horizontal sides of each trapezoidal block is not more than 1/3 of the height of each trapezoidal block; wave-absorbing and pressure-releasing holes can be arranged on the slope surface of each trapezoidal block. The trapezoidal-block embankment structure disclosed by the invention has the technical effects that the foundation pressure is less, the stability against overturning and the stability against the sliding in waves are good, and the capability for resisting accidental impact of floating objects such as ships is strong. The trapezoidal-block embankment structure is applicable to improving embankment structures, wave-wall structures and breast-wall structures of dam engineering such as buildings, breakwaters, sand control dams and revetments in the field of dam engineering.
