摘      要：Ensuring that water flows smoothly into spillways is the main challenge in spillway design. In order to help avoid the formation of vortices and separation of flow along the guide wall in front of the gates during overflow through the spillway, an experiment with a physical model of the Yutang Dam. bank spillway was carried out, The profile of the guide wall was redesigned to eliminate the formation of vortices and separation of flow. This involves opening up holes in the middle part of the guide wall. The test results show that the design is effective in improving the flow conditions of the inlet, and in ensuring the desired values of water head along the guide wall and discharge capacities of the spillway,
