摘要
本文简述了现场浇注混凝土桩的低应变完整性试验的基本理论和方法。文中设定了几个简单的分析模型,利用三维显式有限元法,对有局部材料缺陷桩完成了冲击荷载作用下的动力反应分析,同时,根据分析结果,对低应变完整性检测试验的实施方案,各种因素的影响效果以及试验结果的分析方法等若干问题进行了初步探讨。
In this paper general theory and method of low strain integrity test for drilled cast- in- place concrete pile arc briefly introduced. Dynamic response analysis of some models of pile with material loss for impact load has been completed by three- dimensional explicit clement method. A few problems on practical scheme of test influence effect of several factors and analytical method of test results are preliminarily discussed.
