摘要
采用ANSYS软件,建立支盘桩-土的三维有限元模型,对桩土之间的作用进行接触分析,研究了挤扩支盘桩在荷载作用下位移场、应力场的变化规律和桩土之间的相互作用。分析认为,支盘桩桩侧摩擦力比较小,支盘上斜面及靠近支盘的上、下桩体表面与土体脱开,主要依靠支盘下斜面及桩底承受荷载。
Based on the ANSYS software, the three dimensional finite element model of piles with branch plate and soil was built, the contact analysis on the interaction of pile and soil was made, variation laws of displacement field, stress field and interaction of pile and soil for the piles with branch plate was studied under the action of loading, it is concluded that the pile-side friction force of piles with branch plate is small, the upper slope of plate and soil body are separate, the pile body surfaces of each side of plate are also separate from the soil body, and the load boating capacity mainly depends on the under slope of plate and the bottom of piles.
