基于推导的泄槽底板抗滑稳定安全系数计算式, 运用正交设计的直观分析法进行底板稳定性敏感性分析, 结 果表明阻滑板长度、底板长度和溢流平均速度是影响底板稳定的重要因素。从底板的抗滑稳定角度, 分析及计算底 板最大允许流速范围为15. 33~ 40. 67 m/ s。最后以实际工程为例, 分析了泄槽底板在单一阻滑板加固作用下的抗 滑稳定性以及阻滑板与底板的应力。

On the basis of the deriv ed ca lculatio n formula for the anti2sliding safety coefficient of chute bott om slab, the sensitiv i2 ty ana lysis o f bo ttom slab stability w as performed using the intuitive analysis method w ith o rtho gonal design, which indicated that the leng ths of anti2sliding plate and bottom slab, and t he ov erflow aver age velocity ar e the main facto rs to affect the stabili2 ty . From the perspect ive o f anti2sliding stability , the max imum allow able f low v elo city of the bottom slab was abo ut 15. 33~ 40. 67 m/ s. Based o n o ne practical project , the ant i2sliding stability of chut e bot tom slab and the st ress betw een the anti2sliding plate and bottom slab w ere inv est igated under the reinfo rcement effect of sing le anti2sliding plate.
