碎石桩处理软弱地基设计要点

The gravel pile design point in treating soft foundation

总结了碎石桩设计及施工中的要点及步骤,特别指出在设计中需要全面考虑碎石桩置换率、地基土粉粒含量cρ、粉土埋置深度、原地基的密实度、场地土的均匀性、施工振动挤密等因素,以使碎石桩计算与实际检测结果尽可能一致。

The paper tallies up the gravel pile design and construction important point and step, specially points out that need to consider the transpositional ratio, silty contents ρc, bury depth, original foundation close-grained degree, soil symmetrical nature and construction vibration cram-full etc. factor completely in design, to make the gravel pile calculation in accordance with actually examination result possibly.
