为解决长江八卦洲汊道的治理，进行了定床及动床河工模型试验。提出的整治工程方案已被采纳实施。近年实测资料表明，工程已见成效，成功地防止了右汊内新生圩港的淤积，并缓解了左汊的衰退趋势。对汊道及边滩型河道的演变理论及整治方法提出的新见解，以及取得的整治经验对长江大河的整治有普遍意义。 In order to solve the governance of the Yangtze River Bagua Chau Road, conducted a fixed bed and movable bed river model tests. Proposed renovation project has been adopted to implement the program. The measured data in recent years show that the project has achieved success and successfully prevented the siltation of the newborn harbor in the right bank and alleviated the downward trend of the left bank. The new opinions on the evolutionary theories and remediation methods of Baotou and Beidaohe rivers, as well as the experience gained in remediation, are of universal significance to the remediation of the Yangtze River.
