【摘要】：澜沧江-湄公河航道上哈乐滩具有弯、浅、险、窄、急等特点。根据现场调查资料,结合数学模型计算结果,分析了哈乐滩成滩原因及碍航特性。哈乐滩右岸楠罗河山洪冲出的石块及大卵石堆积在溪口形成冲洪积扇,近年来冲积扇发育,进一步侵占河床泄水断面,同时岸线凹凸不平,导致滩险上段水流弯曲,中段坡陡流急,船舶枯水上滩困难。针对哈乐滩滩险成因及碍航特点,提出炸礁和修筑整治建筑物结合的措施,解决滩险碍航问题。
[Abstract]:Lancang-Mekong channel Hale beach has bend, shallow, dangerous, narrow, urgent and other characteristics. On the basis of field investigation data and mathematical model calculation results, the causes and navigation hindrance characteristics of Hale Beach are analyzed. The rocks and large pebbles flushed out of the mountain torrents of the Nanluo River on the right bank of Hale Beach formed alluvial fan at the mouth of the stream. In recent years, alluvial fans have developed, further encroaching on the drainage section of the riverbed, and at the same time, the bank line is uneven, resulting in the water flow bending in the upper section of the beach danger. The steeply current of the middle slope makes it difficult for the ship to go up to the beach with low water. In view of the cause of formation of Hale beach danger and the characteristics of hindrance to navigation, the measures of combination of reef blasting and building renovation are put forward to solve the problem of hindrance to navigation in Hale beach.
