Examples
- In order to understand the characteristics and mechanism of flow washout for the crevice of core wall in earth - rock dam , according to the exemple of crack washout test for the core of heihe dam , constant water level washout test and changing water level washout test are adopted differently , the process of test and the character of the flow washout for the core crack are gone into particulars
摘要为了解水流冲刷作用下反滤层对土石坝心墙裂缝发展保护作用的特点和机理，以黑河土石坝心墙裂缝冲刷试验为例，分别采用常水头和变水头两种方法，探讨了土石坝心墙裂缝在水流冲刷过程中的特点。 - Abstract : an experimental investigation of local scour around a new type bridge pier under a clear water regime is presented . the main characteristic feature of flow is relatively large horseshoe vortex flow along the circumference of the pier . and the procession of scour is discussed in this paper . equation for predicting the depth and area of local scour hole is presented . it is significant for evaluating the potential for scour around this type pier
文摘:介绍了一种新型桥墩即多腹薄壁墩的局部冲刷试验成果.认为桥墩周围的水流以绕流桥墩的相对较强的马蹄型漩涡系为主要特征.并讨论了冲刷过程，给出了预测冲坑深度及大小的关系式，可供估算同类型桥墩的冲刷参考 - The existing results about scour hole was summarized . experiments was made about the influence of aeration on scour , the dynamic pressure on the original riverbed and the scouring hole bottom , and the influence of aeration on the dynamic pressure and the velocity of submerged jet . scour was simulated by numerical model
在总结前人研究成果的基础上，试验研究了掺气对基岩冲刷破坏的影响；基岩冲刷过程中冲坑底部脉动压强随冲坑深度的增加而变化的特性；掺气对冲坑未形成前河床底部及基岩冲刷坑底部脉动压强的影响；掺气对射流轴线流速变化的影响等。
