摘　　要：阐述了挤扩多支盘桩在软土地区的应用情况,通过现场静载荷试验,分析了钻孔灌注桩和挤扩多支盘灌注桩的承载力,采用高应变动力试验方法,研究了多支盘灌注桩的承载性质,从而提高了支盘的承载力。In this paper, the application of a bored pile with expanded branches in the soft soils was expounded. Based on the results of static load tests, the bearing capacities of bored piles and bored piles with expanded branches were analyzed. And high strain dynamic tests were employed to discuss the behaviors of the expanded branches. So as to improve the bearing capacity of expanded branches.

关 键 词：多支盘桩 静载荷试验 高应变动力试验 承载力
