引言本文论述桩对动力荷载的反应。文巾涉及的范围限于打入粘土中的单个钢管桩,所考虑的动力荷载的上升时间为1—2秒,周期为1—20秒。首先,从现场的桩荷载试验出发建立了桩头的特性,同时汇集了单自由度系统的反应和粘土的实验室试验资料,为在设计中应用桩的荷载试验结果提供了基础。 Introduction This article discusses the response of piles to dynamic loads. The range covered by the text towel is limited to the individual steel pipe piles that are driven into the clay. The rise time of the considered dynamic load is 1-2 seconds and the period is 1-20 seconds. Firstly, the characteristics of the pile head were established based on the site pile load test. At the same time, the reactions of the single-degree-of-freedom system and the laboratory test data of the clay were collected, which provided the basis for the application of the pile load test results in the design.
