摘要
从既有桩顶沉降量又有桩端沉降量及桩身各点位移量的静载荷试验资料入手,分析了钻孔桩的荷载传递和变形性状,揭示了不同规格桩在不同荷载水平下的桩身混凝土压缩量和弹塑性变化规律,并分析了桩身压缩量的影响因素。得出了一些有用的结论。
A multi-parameter static load test method of pile is introduced. With this method,the results calculated with elastic method are compared with the results measured in the field test,and the elastical and plastical characteristics of pile and the influence factors on pile compression are analysed. Some useful conclusions are drawn at last.
