摘　　要：采用改进的溢洪道底板抗浮稳定计算公式,计算了东谷水库溢洪道泄槽的抗浮稳定,经分析,泄槽底板水毁的主要原因是高速水流产生的强大脉动力所致,指出了应汲取的教训。s： Using the improved formula of stability against floating for base plate of spillway, stability against floating of spillway in Donggu reservoir is analyzed. The result shows that spillway damage is mainly caused by powerful pulsating pressure produced in high velocity flow. Further, lessons from this accident are presented, for reference.
