AASHTO T 386-19涵盖了测试垂直或倾斜桩的程序，以确定桩对预选目标峰值力的轴向压缩荷载脉冲的位移响应。这种测试方法适用于所有类似于桩的功能的深基础单元，而不管它们的安装方法。

This method covers the procedure for testing a vertical or inclined pile to determine the displacement response of the pile to an axial compressive load pulse of a preselected target peak force.This test method is applicable to all deep foundation units that function in a manner similar to piles, regardless of their method of installation.Two alternative procedures are provided:Procedure A uses a combustion gas pressure apparatus to produce the required axial compression force pulse.Procedure B uses a cushioned drop mass apparatus to produce the required axial compression force pulse.The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in the design or other uses.This standard was formerly designated as provisional standard TP 104.
