使用粉煤灰淤筑的淤背体比使用黄河粉沙土淤筑的淤背体具有更大的抗剪强度 ,并且随着淤背体固结时间的延长 ,这一差距将逐渐扩大。因此 ,使用粉煤灰淤筑的淤背体具有更大的抗滑移、抗坍塌及抗倾覆能力 ,在同样的外界条件下也具有更大的稳定性。
The silt dredged with fly ash has greater shear strength than silt dredged silty sand in the Yellow River, and this gap will gradually widen with the consolidation time of silt dorsal body. Therefore, the use of fly ash silt dredging back body with greater anti-slip, anti-collapse and anti-capsize ability in the same external conditions also have greater stability.
