【摘要】：2016年汛期长江发生大洪水,长江中游韦源口河段左岸黄冈长江干堤茅山堤团林段发生崩岸险情,经现场紧急抢险,情况得到有效控制。对险情发生的原因进行了分析,介绍了具体的抢险措施,并就此次险情的后续整治和韦源口其他相关河段河道治理措施进行了研究。针对茅山堤团林段的河势情况,提出了今后该河段治理时,应开展水文、水下地形测验,对岸坡的稳定性进行评价,必要时对险情段抛石加固和对上、下游受回流影响段进行新护,适当平整险情附近段岸线,严禁崩岸附近河段非法采砂;对其他河段现有护岸工程进行加固和延护,稳定现有河势和主流位置,整治牯牛沙水道,改善航道条件等治理措施。其成果可供规划设计单位或管理部门参考。
[Abstract]:During the flood season in 2016, the Yangtze River was flooded and the bank collapse danger occurred in the left bank of the Weiyuankou reach in the middle reaches of the Yangtze River. After emergency rescue on the spot, the situation was brought under effective control. This paper analyzes the causes of the danger situation, introduces the concrete emergency measures, and studies the follow-up treatment of the danger situation and other relevant river channel control measures in Wei Yuankou. In view of the river regime of Maoshan dike forest section, it is put forward that in the future, hydrology and underwater topographic test should be carried out, the stability of bank slope should be evaluated, and if necessary, the dangerous section should be strengthened and leveled. The downstream section affected by the backflow shall be protected by new measures, the shoreline of the section near the danger situation shall be properly leveled, illegal sand mining in the section near the bank will be strictly prohibited, and existing revetment works in other river sections will be strengthened and extended to stabilize the existing river regime and mainstream position, and renovate the Guliusha waterway. Improve waterway conditions and other management measures. The results can be used for reference by planning and design units or management departments.
