长江小米滩位于泸州市下诲约五公里,因上浅下险而著称。通过定床、局部动床河工模型试验,建议采用筑坝(毛线碛上建两条下挑丁坝)与疏浚相结合治浅和水下潜坝(下深槽雨丘石附近两座潜坝)消泡治险。78年冬至79年春丁坝施工。80年冬至81年春潜坝和挖槽施工。竣工后滩段水流调顺,横流减弱,泡水消散,航行条件明显改善。并为治理同类复杂的浅险滩积累了成功的经验。
Xiaomi beach in the Yangtze River is located about five kilometers under the guidance of Luzhou City, known for its superficial under-dangerous. Through the fixed bed and partial movable bed river model tests, it is suggested to combine the dams with the dams to construct the shallow dam and the underwater dive dam (two submarines near the lower hedge rock) Defoaming treatment. 78 years winter to 79 years spring dam construction. 80 years from winter to 81 spring submersible dam and trenching construction. After the completion of the beach section of the water flow Shun, cross flow weakened, bubble water dissipated, navigation conditions improved significantly. And has accumulated successful experiences for the management of similar complex shallow and dangerous beaches.
