单位桩周侧阻力值的影响因素研究

沿桩周处取脱离体与在桩底处取脱离体进行比较,就可明显看出,桩底土的强度、桩的长度及桩径粗细均对桩的侧阻力有较大的影响。因此对提供的勘察资料应根据不同条件合理取值,才能符合实际情况。

Study of Pile Side Frictional Resistance′s Influence Factor

By comparison of the properties of the free body taken pile surface with those from the pile tip,it is quite obvious that many factors like soil layer strength at pile tip,pile length and pile diameter will all have substantial influence on pile side frictional resistance.Therefore,care should be taken to evaluate the engineering properties of the soil layers in survey report in accordance with different conditions so as to be fallied with real circumstances.
