摘　　要：变形监测控制网具有提供监测基准和维护基准长期稳定的重要作用,但涉及大量平差数学模型和稳定性分析统计模型,已远超常规平差软件功能体系。精密变形监测网数据处理系统(DefDPS)集成了完备的控制网全生命周期数据处理功能要素,具有强大的任意基准多模型组合平差计算功能和多模型协同点位稳定性综合分析功能,建立的平差计算与稳定性分析协同机制可高效筛选出稳定平差基准,对变形监测控制网保障基准长期稳定具有实际作用,值得推广到类似工程测量控制网项目中。Deformation monitoring control network plays an important role in providing monitoring datum and maintaining long-term stability of the datum,but it involves a large number of adjustment mathematical models and stability analysis statistical models,which is far beyond the functional system of conventional adjustment software.The DefDPS integrates complete functional elements of data processing through the whole life cycle of control network,and has the multi-model combined adjustment calculation function for any datum and the multi-model comprehensive analysis function for point stability.The established synergy mechanism between adjustment calculation and stability analysis can efficiently select the stable adjustment datum,which has a practical role in ensuring the long-term stability of datum for deformation monitoring control network.Thus,it's worth popularizing to similar engineering survey control network projects.
