摘要
根据地球固体潮的有关理论，从物理大地测量的角度推导了建筑物负荷引起的地面和大地水准面的形变量的计算公式，并通过模拟计算，对单幢高层建筑、城市建筑群以及环形高架桥引起的附近地面和大地水准面的形变情况进行了定量分析。计算结果表明：建筑物负荷引起的地面垂直形变量要比水平形变量和大地水准面形变量大，城市建筑群引起的附近地面和大地水准面的形变量可达几毫米，对实际测量结果有一定的影响。
The earth is elastic, and any loading on its surface may lead it to elastic deformation. In this paper, based on the solid tide theory of the elastic earth, the ground and geoid deformations caused by loading of neighboring buildings are studied. The deformations caused by a large scale building, sets of buildings, and a flyway are calculated respectively as examples. The results show that the vertical deformation caused by building loading is larger than the horizontal deformation and geoid deformation, the ground and geiod deformations caused by sets of buildings may reach several millimeters magnitude normally.
