【摘要】：钢筋石笼是截流、堵口和护岸工程中常用的一种人工材料,探索钢筋石笼的稳定性机理对指导其合理应用具有重要的意义。为研究空隙率对钢筋石笼稳定性的影响,针对不同形状及不同空隙率的钢筋石笼进行了起动试验,拟合提出了考虑其空隙率的钢筋石笼起动流速公式,对块体抗冲流速经典公式进行了补充和完善。研究表明:在其它影响因素相同的情况下,钢筋石笼的空隙率越大越稳定,且不同形状的钢筋石笼的稳定性有所不同。最终得到了包含大小、密度、形状、相对粗糙度等因子的钢筋石笼起动流速计算公式,经试验验证该公式具有较好的计算精度。
[Abstract]:The reinforcement and stone cage is a kind of artificial material commonly used in the closure, plugging and revetment engineering. It is of great significance to explore the stability mechanism of the reinforcement and stone cage to guide its rational application. In order to study the effect of the void ratio on the stability of the reinforcement stone cage, the starting test of the reinforcement stone cage with different shapes and different void ratios is carried out and the fitting is put forward. The classical formula of the block impact velocity is supplemented and perfected by the formula of the starting velocity of the reinforced stone cage with the clearance rate. The study shows that the void ratio of the reinforced stone cage is more stable and more stable under the same influence factors, and the stability of the steel cages with different shapes is different. Finally, the size, density, and shape are obtained. The formula for calculating starting velocity of reinforced concrete cages with relative roughness and other factors is verified by experiments.
