摘　　要：在某电厂桩基静载荷试验的基础上利用数值模拟软件,分析了支盘桩的竖向荷载传递规律、单桩垂直承载力、承力盘对桩的承载力的影响及在承载过程中形成的应力场.为将来更进一步研究支盘灌注桩的荷载传递过程及合理确定支盘灌注桩的承载力提供了参考依据。Based on pile foundation static loading test results, numerical simulation software is used to analyze the laws of vertical load transfer of branch pile, vertical load bearing capability of single pile, effects of plate on pile＇ s load carrying capacity, and stress field formed during load carrying, are analyzed, providing basis for further studying on load transfer process and determining carrying capacity of branch cast-in-place piles.
