摘　　要：桩顶嵌固在承台中的弹性长桩群桩基础的实际工作性状非常复杂 ,在清华大学综合体育中心工程中 ,为掌握大跨度拱结构基础桩的受力变形情况 ,在工程施工过程以及结构竣工后一年时间内对基础桩的应力进行了持续监测 ,获得了大量的数据 。The actual working behaviours of a group pile foundation of elastic long piles with their heads fixed to the cushion caps are very complicated.For Multipurpose Sports Center of Tsinghua University,a continuous monitoring of the foundation pile's stresses was conducted within a year after the completion of its structures and during its construction in order to understand the stressed deformations of the foundation piles for the large\|span arched structure,by which a large amount of data was obtained.A comparison was made between these data and those from the horizontal static load test of the piles at the site.
