摘　　要：多头小直径深层搅拌桩是利用水泥等材料作为固化剂,通过专用的多头小直径搅拌机械,将地基土和固化剂强制搅拌,固化剂和地基土之间产生一系列物理化学反应后凝结成具有一定厚度、强度和抗渗性能的连续桩体。介绍了该桩在某水库大坝截渗中的应用,指出多头小直径在土石坝、堤防截渗中具有造价低、功效快的特点,具有广泛的推广应用价值。Long small - diameter deep mixing pile is the use of cement and other materials as curing agent, through a dedicated long small - diameter mixing machinery, will be a mandatory foundation soil mixing and curing agent, curing agent and produce a series of foundation soil physico - chemical reactions between the post -condensation as having a certain thickness, strength and impermeability of the continuous pile. This article describes the piles in a reservoir dam in the application of cutting seepage, pointing out that small - diameter long embankment dam, dike cutting seepage has a low cost and effectiveness of block features, an extensive application of worth.
