摘要

天然河道中弯曲边坡是受侵蚀的严重区域,弯曲边坡防护是河道治理的重大难题。基于生态护坡理念,对比研究了砂石填装的不同形状抛枕在弯道侵蚀中的防护效果。根据实际河道结构,构建了弯道河床几何模型,进而利用计算流体力学-离散相模型(CFD-DPM)方法分析在弯曲河道凹岸侧投放长方体、半球体和半圆柱体抛枕的护岸效果。分析结果表明:在水流速度v=0.5 m/s的条件下,放置有抛枕的3种模型中,长方体抛枕附近的凹岸受到的压力最小,半圆柱体抛枕中颗粒雷诺数最小;半圆柱体抛枕阻挡的颗粒量最多、颗粒的平均速度最小,比无抛枕模型中的颗粒平均速度小9%;放置长方体抛枕的护岸模式下,对抛枕附近的凹岸有较好的防护效果,放置半圆柱体抛枕的护岸模式下,阻沙效果最佳。

Abstract

Curved slopes in natural river channels are highly susceptible to erosion, posing a significant challenge for river management. To address this issue, a comparative study was conducted on the protective effects of sand-and-gravel rip-rap bags of different shapes against erosion based on the concept of ecological slope protection. First, a geometric model of the curved-channel bed was constructed according to the actual river structure. Then, the CFD-DPM method was employed to analyze the bank-protection effects of rectangular, hemispherical, and semi-cylindrical bags placed on the concave bank of the curved channel. Results revealed that under a flow velocity of 0.5 m/s, among the three shapes of protection bags, rectangular bags bring about the least pressure on the concave bank, while semi-cylindrical bags obstruct the largest amount of sediment particles, leading to the smallest Reynolds number of particles and the minimum average particle velocity, 9% lower than that in the model without protection bags. In conclusion, rectangular rip-raping bags offers better protection for the adjacent concave bank, while semi-cylindrical bags provide the most effective sand-blocking function.

摘要

抛石护岸历史悠久，在长江中下游及国内外各大河流中应用较为普遍。通过对块石与小颗粒石料的不同铺护方案及块石定点投抛的试验研究，结果表明，抛石是较为理想的护岸材料，能很好地适应河床变形，粒径越小，其适应河床变形的能力越强。抛石护岸工程效果与其粒径、覆盖率及石方量等有关。抛石在施工过程中，在水深流速大的地方可做到在床面分布上相对比较均匀。

iprap protection of bank was applied in the middle and lower Yangtze River and many other rivers at home and abroad. The experiments on many riprap protection schemes of different diameters were carried out. The test results are summarized as follows: It could better adapt change of river bed. The less the diameter of block stone is, the stronger the ability adapting change of river bed is. Effect of riprap protection is related to the diameter, percentage of coverage and cubic meter quantity of block stones. During the process of revetment construction, it has a uniform distribution on bank slope at the place of high water depth and big velocity.

摘要

近50年来长江中下游河道演变分析表明,河道演变具有如下特点:河道总体河势基本稳定,局部河势变化较大;河道总体冲淤相对平衡,部分河段冲淤幅度较大;荆江和洞庭湖关系调整幅度加大;人为因素未改变河道演变基本规律;坐崩是长江中下游岸线崩退和护岸工程崩毁的主要形式;人为因素对长江口河道演变的影响增加。

摘要

近年来，国内在江河护岸工程实践过程中，创新优化出了预制混凝土铰链沉排护岸的新型结构形式，在多个护岸工程中得到成功应用并取得了良好的防洪护岸效果，但由于其水下排体尺寸较小，施工完成后水下部分的铺设情况很难被准确探测出来，也为水下部分的施工质量进行质量评定带来了困难。在对目前各种水下检测技术进行充分对比分析的基础上，提出超高分辨率多波束测深技术，并利用该技术成功地应用于长江武汉段铰链沉排护岸工程的水下部分施工铺设情况的勘测。实践证明该技术在定量检测预制混凝土铰链沉排工程水下铺设质量方面具有较大的优势，并可作为类似工程水下部分质量检测的技术手段。
