For distributive mixing ability, KB120/120 and FTX showed excellent performance on distributive mixing ability, because they had the greatest backflow and the widest distance between inflexions of RTD curve respectively.

对于分布混合能力，由于物料在流经错列角为120°的捏合盘元件时回流量最大，在流经六棱柱元件时停留时间分布曲线拐点间的距离最大，因此这两种元件的分布混合能力很强。

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

新桥深凹露天矿边坡岩体的原位剪切试验、点载荷试验、室内模拟AMD作用试验表明：AMD蚀化后的石英砂岩，岩体层面间的抗剪强度和粘聚力减小的幅值约为13.2%~21.3%；层面间内摩擦角减小幅值在5.0%~7.5%之间；AMD一般影响垂直边坡体内部在60~100m范围内的岩体力学性质数值分析表明：AMD对边坡体的作用主要集中在弱化区域内，边坡体的底脚和AMD作用中心区域的剪切应力减少了52.0%和64.7%；(2)随着边坡体高度和距离的增加，远场爆炸应力波对边坡扰动幅值的增加趋势明显，边坡顶部和断层部位的响应突出，损伤效应明显；边坡底脚扰动幅值最小，临空面附近台阶的扰动幅值明显大于边坡体内部；(3)AMD与爆破荷载耦合作用后，边坡体内部的应力分布主要呈现出爆炸应力场的特征，AMD影响区域形成了一个剪切应力弱区。

Thus the working mechanism of the rigid foundation has been demonstrated. The back pressure varies much at initial stage, which largens in corner point area and lessens in center area.

刚性基础在荷载作用下，计算区域基底反力在加荷初期变化比较大，角点区域反力变大，中心区域反力变小，随着时间的增长，反力逐渐趋于稳定。
