在渠系衔接建筑物中,陡坡消力池是常见的消能形式,其中以菱形陡坡消力池较为新颖且性能良好。菱形陡坡具有独特的坡面外观而区别于常规形式。自缺口开始,坡面先扩散后收缩,使消力池中水跃的跃首恰好发生在菱形坡面最大宽度处,从而形成共轭断面内约略相等的水面宽度,并有效地克服了梯形断面消力池所特有的旁侧回流,这样就大大增加了消力池的消能效果。菱形陡坡消力池最早应用于苏联中亚细亚的灌溉渠道上,并由苏联学者 A.A.马什 Steep sloped troughs are common dissipative forms in canal-connected buildings, of which the troughs with rhombic steep slopes are relatively new and well behaved. Rhombic steep slopes have a distinctive slope appearance unlike conventional forms. Since the beginning of the gap, the slope first expands and then shrinks, so that the jump of water jets in the stilling pool occurs exactly at the maximum width of the rhombic slope, resulting in approximately equal water surface widths in the conjugate section and effectively overcoming the trapezoidal section Stirring pool of the unique side of the backflow, thus greatly increasing the energy dissipating effect of the pool. The rhombic steep slope trough was first applied to the irrigation channels in the Central Asia of the Soviet Union and was started by the Soviet scholar A.A. Marsh
