现代建筑物结构材料的不断完善使得现代高层建筑的整体性质趋向于刚体。因此可根据质点系(刚体)动力学原理,将高层建筑物视为刚体模型来研究其整体形变。针对这一前提本文设计并研究了高层建筑物的监测点布设方案及观测方案,提出了整体形变模型,探讨用拟稳平差来计算监测点精确坐标;针对高层建筑物顶部在风荷载条件下的变形情况,本文采用差分GPS进行连续观测,以获得其运动规律。
現代建築物結構材料的不斷完善使得現代高層建築的整體性質趨嚮于剛體。因此可根據質點繫(剛體)動力學原理,將高層建築物視為剛體模型來研究其整體形變。針對這一前提本文設計併研究瞭高層建築物的鑑測點佈設方案及觀測方案,提齣瞭整體形變模型,探討用擬穩平差來計算鑑測點精確坐標;針對高層建築物頂部在風荷載條件下的變形情況,本文採用差分GPS進行連續觀測,以穫得其運動規律。

Continuous improvement of modern building construction materials changes the overall nature of the modern high-rise buildings to be rigid. Therefore, according to the system of particles (rigid) kinetic theory, we can take the high-rise buildings as a rigid body model to study its overall deformation. On this premise, this paper designed and studied monitoring sites setting programs and observation programs of high-rise buildings, proposed overall deformation model, discussed to calculate the exact coordinates of monitoring points by quasi-stable adjustment. According to the deformation situation of wind load at the top of high-rise buildings, the differential GPS was used for continuous observation to get its motion law.
