高坝泄槽隔墙静动力稳定分析
Static and dynamic stability analysis on chute partition wall of high dam
摘要
Abstract
A mode of dissipation, other than the traditional one, with upper and lower flip buckets and multiple submerged jets is adopted on a concrete gravity dam constructed in China; for which a partition structure is arranged on the middle of the overflow section of the dam for discharging the flood at all the relevant levels and adjusting the flow pattern of the project However, not only the flow pattern therein is quite complicated, but the problems from both the dynamic response and stability are more extrusive, as the dam surface partition wall is just located in front of the hydraulic jump to the plunge pool. In accordance with the safety problem from the engineering practice concerned, the static and dynamic characteristics of the surface partition wall of this dam under the complicated operation condition are analyzed based on the model test combined with the related numerical simulation ; in which the relationship between the structural character and the safety of the flow-induced vibration is discussed and then its stability is evaluated as well. The conclusion shows that some appropriate measures for strengthening the chute partition wall of the project must be made during the structural design concerned, furthermore, this study result can also provide a reference for the similar project in the days to come.关键词
