Standard Method of Test for High-Strain Dynamic Testing of Piles
桩的高应变动态试验的标准试验方法
本试验方法涵盖了单独测试垂直桩或斜桩的程序,以确定桩对打桩锤轴向施加在桩顶部的冲击力的力和速度响应。这种测试方法适用于类似于基桩的功能的深基础单元,无论它们的安装方法如何,只要它们能接受高应变冲击测试。这些元件包括钻孔桩、微型桩和连续螺旋钻孔灌注桩。除第5.2节外,本标准总体上符合ASTM D 4945。
This test method covers the procedure for testing vertical or batter piles individually to determine the force and velocity response of the pile to an impact force applied axially by a pile-driving hammer to the top of the pile. This test method is applicable to deep foundation units that function in a manner similar to foundation piles, regardless of their method of installation, provided that they are receptive to high-strain impact testing. These elements can include drilled shafts, micropiles, and continuous flight auger cast piles.Except for Section 5.2, this standard is in general conformance to ASTM D 4945.
