By means of mathematical model and ship handling simulation test，we analyze the navigation obstruction characteristics of the sharp bend channel in the reservoir area under the operation condition of low water level of the pivot，and improve the navigable conditions by optimizing the navigation scheme and adjusting the position of the anchorage. The results show that the ship’s traverse speed and drift can be significantly reduced by taking advantage of the large range of slow flow zone in the concave bank of the Matouling sharp bend section，and adopting the navigation scheme that the ship enters the slow flow zone along the right bank first，turns down and then leaves for the downstream. When the anchorage is adjusted from the front of the lock to the slow flow zone at the top of the bend，the circumferential water required for anchoring is significantly reduced，the traverse speed is only 0.4 m/s，and the maneuvering risk of lifting anchor into the lock is also lower. The above non-engineering measures play a positive role in ensuring the navigation safety of the sharp bend section.
