摘要：

泥浆性能直接影响钻孔桩的承载力和桩侧摩阻力。讨论分析了建筑和公路桥涵施工规范对泥浆材料和性能指标的规定,指出了泥浆材料和性能指标是与钻孔桩的施工工艺、桩的规格、土层条件以及设计桩侧摩阻力的要求密切相关。

Property of slurry has direct impact on the bearing capacity and skin friction of bored piles. Stipulations in relevant construction codes for buildings, and highways, bridges and culverts on the material and performance index of slurry are discussed and analyzed. The results of the analysis show that the material and performance index of slurry is closely correlated to construction technology and size of the bored piles, soil conditions and the design considerations for skin friction.
