基于原型沉降监测资料的面板坝正反分析研究

Analysis and Study on CFRD Inversion Based on Prototype Settlement Monitoring Data

利用公伯峡水电站原型观测资料反演面板坝的土体材料参数,获得新的材料参数。将新参数代入模型,结果表明反演参数能较为真实地反映大坝运行性状。通过对比反演参数和试验参数,对各分区材料设计施工进行了评价。分析了大坝各堆石区材料特性、施工质量,为面板堆石坝堆石体设计施工提供一定的参考依据。

By application of the prototype monitoring data of Gonghoxia Hydropower Station, parameters of soil materials of CFRD is derived from inversion, Accordingly, new material parameters are obtained. The new data are substituted in the model. It presents that the inversion parameters can truly reflect the dam operation characters. Through comparison of the inversion parameters and the test parameters, design and construction of materials in zones are evaluated. Material characteristics and construction quality of rock fill zones are analyzed. This provides design and construction of CFRD rockfill mass with reference.
