在过水围堰中,堆石过水围堰块石护坡施工最简单、且能充分利用当地材料,一般造价也较低,从而在国内外得到广泛的应用。 一、本问题国内外研究现状的短评 (一)苏联以伊兹巴斯为代表的研究工作 假定下游边坡上块石的失稳方式是滚动,由力矩平衡方程,配合水力模型试验,得到边坡上平均流速与块石化引直径d_s之间存在下列方程式: In the cofferdam, rockfill overcrowding cofferdam stone revetment construction is the simplest, and can make full use of local materials, the general cost is also low, which have been widely used at home and abroad. First, the present situation of domestic and foreign research short comment (A) The Soviet Union to Izbasi as the representative of the research work Assuming downstream rock slope on the slope of instability is rolling, by the moment balance equation, with the hydraulic model test, the edge The following equation exists between the average flow velocity on the slope and the diameter d_s of block petrochemistry:
