The research is according to the underset energy dissipation problem of the release works in xianmi hydropower station in Xianmi village, Men Yuan county, Qinghai province.

本研究是针对青海省门源县仙米乡仙米水电站泄水建筑物的底流消能问题进行的。

After experimental data processing, material's viscousness coefficient was acquired and a new method to determine fatigue limit by the threshold of plasticity energy dissipation was given.

通过对试验数据的分析，求出了材料的黏性系数，给出了利用塑性能耗的起点确定材料疲劳极限的方法。
