To protect the safety of bridges and improve the flood discharge capacity of rivers, the impact of several different types of streamlined bridge piers on the height of water blocking in front of the piers was studied. Based on numerical simulation methods, k was proposed as the shape coefficient of streamlined bridge piers to characterize the relative size of the radius of the streamlined anti arc to the pier width. The water blocking height of various streamlined bridge piers was compared. The results indicate that with fixed pier length, width, and spacing, changing the shape of the pier will affect the maximum water blocking height in front of the pier; Increasing the shape factor k will reduce the maximum water blocking height in front of the pier; At the same k value, optimizing the pier head to reduce backflow is better than optimizing the pier tail, and optimizing both the pier head and tail has a better effect. This conclusion can provide reference for practical projects such as bridge construction and river management.
