摘　　要：支盘桩是一种变截面的摩擦端承桩,具有高承载力和低沉降特性的新型桩基.为了探求支盘桩竖向沉降规律,通过数值方法和静载荷试验对支盘桩固结沉降规律进行了系统的理论分析及试验研究.数值分析结果和试验研究结果表明,支盘直径的增大桩竖向的固结沉降低,而且支盘桩沉降以固结为主.从而,为挤扩支盘桩在长春粘性土地基中的应用,提供了理论及试验依据.The squeezed branch pile is a new type of frictional end-bearing pile with high bearing capacity and low settlement. By studying the settlement rule of the squeezed branch pile, the theory and experiments of the pile is studied by the method of numerical simulation and static load test. The consolidation settlement of squeezed branch pile becomes small with its increasing diameter of squeezed branch, and is the main part in the settlement of the squeezed branch pile. So the application of squeezed branch pile is supported in clay base of Changchun by studying those rule.
