摘　　要：在动水环境及大粒径地层条件下,采用新二重管法对船坞围堰地基进行防渗处理,通过改进施工措施,有效地解决了大粒径地层钻孔难以及动水环境下浆液易稀释和流失等问题,对块石含量较高、地下水流速较大的大粒径地层的地基防渗加固提出了可行的施工方案。Under the condition of hydrodynamic and formation with large-particle,a new JSP technique was applied in the anti-seepage for the foundation of a dock cofferdam.The difficulty in drilling of the large-particle formation,as well as the dilution and loss of slurry in hydrodynamic condition,have been solved effectively through the improvement in construction.A feasible technique was proposed accordingly for the seepage and reinforcement of the formation with high rock content and high groundwater velocity.
