摘　　要：为了了解全套管灌注桩的承载性状及施工技术,在某一项目勘测现场对桩基进行了静载荷试验,并采用ADINA有限元程序进行数值分析计算,得到了一些试验数据并通过处理数据绘制出Q-S曲线。经过对模拟试验中得到的有代表性的Q-S曲线进行分析研究,可知这些Q-S曲线具有明显的双曲线特征,以此来研究全套管灌注桩的承载性状并对实际工程中的施工技术进行研究。In order to understand the bearing characteristics and design technique of the complete set of piping arrows,the static load test of the pile foundation was performed at the survey site of a project,and the ADINA finite element program was used for numerical analysis and calculation,and some test data was obtained and the Q-S curve was drawn by processing the data.By analyzing and examining the representative Q-S curves obtained in the simulation test,it can be determined that these Q-S curves have obvious hyperbolic properties to study the bearing properties of the entire set of piping arrows and study the design technique in the actual project.
