| 摘 要： | 通过实际和模拟例子讨论了缓慢沉降地区的监测资料数据处理问题。指出逐级平差方法有可能造成沉降量估计偏差过大；在地面沉降较为缓慢时，这种偏差甚至会导致对地面沉降的错误结论。最后提出了改进方法。

| Abstract: | Monitoring data processing method in slow land subsiding area is discussed through a real example and simulations. It is pointed out that by means of separated adjustment according to leveling order the error of land subsidence is possibly too large, it even leads to a incorrect conclusion. And an improvement is proposed at the end of this paper. |
