摘　　要：工作基点的坐标是由各基准点的已知坐标延测过来的,假设基准点发生了明显变动,但仍将基准点视为已知点,则工作基点和变形监测点的坐标都必将受到干扰。本文以开封市民之家工程为研究对象,探讨建筑变形监测中基准点稳定的重要性。The coordinates of the working base point are extended from the known coordinates of each reference point. Assuming that the reference point has changed significantly, but the reference point is still regarded as the known point, the coordinates of the working base point and the deformation monitoring point will be disturbed. This paper took Kaifeng Citizen’s Home Project as the research object, and discussed the importance of reference point stability in building deformation monitoring.
