长江三峡库区炉子梁孤礁炸礁水深的确定及整治效果分析

Identification of blasting depth and analysis of regulation effects of Luziliang isolated rocks in reservoirs of the Three Gorges Dam

以长江三峡库区炉子梁碍航孤礁为研究对象,通过解析解、数学模型和概化水槽模型试验等手段,论证了孤礁浅水效应下水面降落和船舶下沉量,并结合长江干线航道发展规划及船舶大型化发展趋势,确定最终的炸礁水深。工程实施后,航槽拓宽,航道维护及航行安全均得到了有效保障,取得良好的整治效果。

Taking the isolated rocks in Luziliang reach in the Three Gorges Dam as the research object, the falling of water surface and the squat of ships is demonstrated using analytic sol simplified flume model tests.Considering the planning of the Yangtze River waterway and , mathematical model and the trend of bigness ships, reef blasting depth is determined.After project implementation, the channel has been broadened, and the channel maintenance and the sailing safety are guaranteed.The regulation effects are good.
