大坝变形监测网平差模型优化设计

Optimization design of adjustment model for dam deformation monitoring network

介绍了水利工程大坝变形监测网数据处理的平差模型。在观测值和平差模型的系数矩阵同时存在误差的情况下,运用传统平差模型处理监测网的观测数据精度较低,无法满足变形监测需要。通过附加限制条件的平差模型优化,能对测量数据进行有效处理,消除和削弱观测值和模型系数矩阵的误差,提高监测网的解算精度,为大坝变形分析提供精确数据。

The problem of urban water supply of Qinzhou City was analyzed, including single water source and in- sufficient supply in the future, based on which two alternatives were put froward. After being compared with the al- ternative of water transfer from Maolingjiang River in respects of water supply reliability, cost and other construc- tion conditions, the scheme of water delivery from Tunliu Reservoir was recommended. An introduction was made on the general layout and other basic information of the selected scheme.
