摘　　要：针对沉降监测得到的数据光滑性不好以及对其等时距化导致的预测结果不准确、精度不高的问题,提出一个改进后灰色预测模型,并利用这个模型对河东机场的信标台、雷达台的沉降监测中不稳定观测点的沉降量进行预测,得到这两个建筑物监测结束后的稳定情况。An improved unequal time-interval gray prediction model for ground subsidence monitoring data is developed in this paper. It improves the accuracy of data by the enhancing the smoothness of the original observations Forecast on the subsidence trend of unstable points of the navigation tower and radar station in Hedong Airport is also given for the stability.
