摘　　要：沉降观测中,有时会出现沉降监测点标高上升的情况。关于测点标高上升的原因,目前尚无明确的解释。结合某工程地基加固过程中沉降监测实例,分析基准点下沉、测量误差、地基土扰动、地下水位变化等原因对沉降监测点标高上升的影响,为沉降监测工作中此类问题的解决提供参考。In settlement observation,elevation rise of settlement monitoring points sometimes occurs. There is no clear explanation for the reason of elevation rise of observation points. This paper analyzes the influence of base-point subsidence,measurement error,foundation soil disturbance,groundwater level change and other factors on the elevation rise of the subsidence monitoring point in combination with the subsidence monitoring example in the process of foundation reinforcement of a project,and provides a reference for the settlement monitoring.
