施工规范对钻孔桩泥浆性能的规定与分析

Analysis and Requirements of Construction Code for Slurry Property of Bored Pile

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。

The slurry property has effect on the bearing capability and skin friction of bored pile and the different requirements of building from highway and bridge for slurry material and slurry property are discussed. The analysis results show the choice of slurry material and slurry property parameters is correlated to construction technology and the size of bored pile, soil conditions and the design requirements for skin friction.
