【摘要】：泄水建筑物在高速水流的作用下常發(fā)生空蝕破壞,通常工程中采用摻氣減蝕措施來達(dá)到對水工建筑物保護(hù)的目的。為了總結(jié)不同的水流摻氣布置型式在高水頭大流量的泄流建筑物中的可利用性和重要性,以及各自的主要特點(diǎn)及優(yōu)缺點(diǎn),綜述了不同型式的摻氣措施的結(jié)構(gòu)、原理和工程應(yīng)用;并對在不同的水力條件下?lián)綒庠O(shè)施布置型式的優(yōu)化選擇及摻氣設(shè)施布置型式的相關(guān)研究進(jìn)行了總結(jié)與展望。
[Abstract]:Cavitation erosion is often occurred in draining structures under the action of high speed water flow. In general, aeration erosion reduction measures are used to protect hydraulic structures. In order to summarize the availability and importance of different flow aeration arrangements in large discharge structures with high water head and large discharge, as well as their main characteristics, advantages and disadvantages, the structure, principle and engineering application of different aeration measures are summarized. The optimal selection of aeration facilities under different hydraulic conditions and the related research of aeration facilities layout are summarized and prospected.
