Abstract TU449; 为指导越江泥水盾构隧道施工过程中的泥浆性质动态调节,以羧甲基纤维素钠(CMC)和粉细砂为主要调控材料,对不同配比泥浆进行密度、黏度、胶体率测试,并基于API滤失试验研究各配比泥浆的滤失性状及泥膜的渗透特性.结果表明:钠基膨润土-粉细砂-CMC泥浆体系具有良好的分散性,泥浆胶体率普遍在98％以上;对于生成泥皮+渗透带型的砂砾地层,虽然通过掺加粉细砂可有效堵塞地层,减小滤失量,但其形成的泥膜渗透系数和滤失量则相对较大;对于需要快速在开挖面形成泥皮型泥膜的地层,增加CMC的掺量可以有效减小泥膜形成时的滤失量,降低泥膜渗透系数;但CMC掺量过大后所成泥膜孔隙比增大,结构疏松,渗透系数反而呈增长趋势.施工过程中可结合实际需求对泥浆性质进行动态调整,以保障泥水盾构掘进和开舱安全.
