在进行沉降观测时,一般认为基准点是固定不动的,而实际上并非如此。若基准点发生了变动,而在数据处理时不加以考虑,便会产生不正确的结果,导致监测点沉降出现异常情况,影响工程施工与运营。本文给出了基准点沉降对监测点影响改正模型,通过对基准点和沉降量进行改正的方法,得到改正模型,并通过武咸城际铁路实际数据进行计算分析,得出了有益的结论。
在進行沉降觀測時,一般認為基準點是固定不動的,而實際上併非如此。若基準點髮生瞭變動,而在數據處理時不加以攷慮,便會產生不正確的結果,導緻鑑測點沉降齣現異常情況,影響工程施工與運營。本文給齣瞭基準點沉降對鑑測點影響改正模型,通過對基準點和沉降量進行改正的方法,得到改正模型,併通過武鹹城際鐵路實際數據進行計算分析,得齣瞭有益的結論。

When settlement observation, it is generally considered that the datum points are fixed, while it is not the fact. Data processing will produce incorrect results without considering the change of the datum points, lead monitoring points settlement to abnormal situations, affect the engineering construction and operation. The Correction Model of moni- toring points affected by datum points settlement is proposed. , The correction model is based on the datum points and set- tlement corrections. Verified by Wu - Xian inter - city railway's project, it is indicating that the proposed method is feasi- ble.
