[提要]  介绍了陕西省邮政电信局网管中心大楼主体结构封顶时的沉降观测和桩项反力、桩间土反力、桩承台内钢筋应力及标高±0.0m处部分钢筋混凝土外筒柱与内筒墙的压应变测试结果，从中可以了解沉降、桩顶反力、桩间土反力、承台内力及首层内外筒柱及墙体竖向变形差依荷载增加的变化情况。其结果可供实际工程设计及超高层简体结构设计计算理论研究参考。
[关键词]  筒中筒结构  沉降观测  桩顶反力  桩间土反力  压应变

The results of field measurement of Net Management Center Mansion of Shanxi Telecom Office are introduced after the roof of mainbody sealed. The measurement includes a series of sub-item, such as settlement observation, pile reaction measurement, inter pile-soil reaction measurement, reinforcement stress measurement of pile-cap and compressive strain measurement of out-tube column and in-tube RC wall. With respect to the increase of the load, the variation of settlement, reaction of pile, reaction of inter pile-soil, inner force of pile-cap and vertical displacement difference between out-tube column and in-tube RC wall is obtained. The results can also be used in real structure design and theory research of super high-rise tube-in-tube structures.
Keywords: tube-in-tube  structures; settlement  observation; reaction; pile; inter  pile-soil; compressive  strain
