变形监测网优化设计二次规划法

Quadratic programming method for optimization of deformation monitoring network

在水工建筑物变形监测的工作中，建立变形监测控制网是保证变形监测质量的基础。网形设计通常系采用模拟法进行。在这里，系根据多目标优化理论，以准则矩阵为目标，以设计变量的改正数为优化变量，建立了适用于同形各级优化设计的通用数学模型。利用该模型，对长江三峡工程的一个实例进行了分析。分析结果表明：该方法是有效的，所得出的优化结果满足变形监测控制网实际分布（网形强度）的需要，优化的方案同经验方案相比可节省大量费用。

in the deformation monitoring of hydraulic structure, to set up the deformation monitoring coneal network isessenhal for ensuring the quality of deformation monitoring. The design of the netwolk condguration is usually made by usingthe analog method. In this paperl based on the multi-objective optimization theory, and taking a criterion matrix as objective , and cormctive values of design variables as optindzation vallables, a general rnathernatical model applicable to optindzation of network configurtion at all levels has been established. A case of TGP was analysed by using this model. The analysed results show that this method is valid, the optithezed results meet the requirement of actual distribution of deformationmonitoring control network or the intensity of network configuration , and a great deal of cost may be saved for an optithezationscheme , compared with the corresponding empiric scheme.
