基于系统误差延续性的附加系统参数模型的基坑监测数据处理

Application of additional systematic parameters for data processing of foundation pit monitoring

本文在引入半参数模型理论的基础上,顾及系统误差的"随机性"与"系统性",重点研究了基于系统误差延续性的附加系统参数平差模型理论,并结合工程实例数据与半参数模型进行比较,得到在处理含有系统误差的监测数据时,基于系统参数延续性的附加参数平差模型要明显优于半参数模型的结果。

The theory of semi-parameter adjustment is introduced firstly considering the system error with the double characteristics of ＇system＇ and ＇random＇.The theory of adjustment with additional systematic parameters is studied in details.For comparing with semi-parameter adjustment,the monitoring data of a foundation pit is processed as an example.It concludes that adjustment with additional systematic parameters based on system continuity is much better than the semi-parameter adjustment.
