纳子峡砼面板砂砾石坝坝料特性试验研究及工程应用

Characteristic and engineering application of material used to the Nazixia concrete panel gravel dam

通过试验对纳子峡砼面板砂砾石坝砂砾石料特性进行了研究分析。确定3B1和3B2料可同区开采,并提出在大坝填筑施工时,3B1和3B2料可不进行区分;同时通过分析碾压试验数据后确定了坝料填筑施工工艺,提出了坝料填筑施工时周边缝的处理方法。

Material characteristic of the Nazixia concrete panel gravel dam were tested.Grit stone 3B1 and 3B2 can be mined within the same district,and used in dam filling construction without distinguishing.By analyzing rolling test data,the dam material filling construction process is determined,and the methods of dealing with the surrounding seam in the dam filling construction materials is put forward.
