摘要
通过桩身埋设特制应力传感器的夯实水泥土桩单桩载荷试验获得的资料,分析了夯实水泥土桩桩身材料的应力应变关系、桩侧摩阻力与桩土相对位移的关系、夯实水泥土桩在荷载作用下轴力、侧摩阻力沿深度的分布特征。并运用荷载传递法结合Geddes公式对试验结果进行了分析,计算与实测数据具有较好的一致性。
Pile loading tests of rammed soil-cement single pile are carried out, in which a new type of stress transducer in pile was proposed. The stress-strain relationship of rammed soil-cement, the non-linear relationship between the shaft resistance and relative displacement of pile shaft, load transfer behavior of rammed soilcement pile and distribution of shaft resistance in single pile are studied according to the loading test data. Based on the method of load transfer and Geddes＇ formula, numerical analysis method for determining loadsettlement relationship of rammed soil-cement pile is developed. Comparison between the results obtained by numerical analysis and the measured data is made, close agreement has been found.
