深圳地区花岗岩地层钻(冲、旋挖)孔灌注桩侧摩阻力参数的取值探讨

Discussion on Side Friction Parameters of Drilling (Punching and Rotary Digging) Bored Piles in Granite Formation in Shenzhen Area

桩的侧摩阻力和端阻力是桩基设计的两个重要岩土参数,尤其桩的侧摩阻力在勘察审图过程中审查师经常会对勘察单位提供的桩基岩土参数提出不同意见,本文以几个典型工程实例,利用桩的静载试验结果,分析和探讨了深圳地区钻(冲、旋挖)孔灌注桩侧摩阻力的取值问题,供大家参考。

Side friction resistance and end resistance of rock and soil are two important geotechnical parameters in pile foundation design. Especially in the process of investigation and mapping,the examiner often gives different opinions on the parameters of pile foundation provided by investigation units. Based on the static load test results of piles,this paper analyses and discusses the value of side friction resistance of drilling (punching and rotary digging) bored piles in Shenzhen area.
