| 摘 要： | 土脑子滩处于三峡水库回水变动区,是川江三大淤沙河段之一.天然情况下,汛期淤沙一般能得到及时冲刷,对航行影响不大.三峡成库后,由于汛后10月份水库开始蓄水,汛期淤沙得不到足够的冲刷,将产生累积性淤积而出浅碍航.本文分析了天然状态下该河段的河床演变特点、碍航原因及三峡成库后该滩段河床演变.并提出了整治设想.

| Abstract: | Tunaozi shoal is one of the famous sediment depositing shoals on the Sichuan section of Yangtze River. It’s on the fluctuation backwater area of the Three Gorges Project. While it is completed, the problem of the accumulative deposition will be more and more severe as deposited sediment on high-water period will not outwashed completely. In this study the regularity of erosion & siltation of the reach under natural condition on 135m, 156m,175m water level. The regulation works on the shoal are introduced in this paper. |
