Taking the restoration project of Chiling Beach in Tufu Bay as an example，this paper analyzes the feasibility of shortening sand barrier length without affecting navigation conditions for optimizing the sand barrier structure. The plan adopts the beach berm nourishment technology and shortens the sand barrier length to 150 m，with sand allowed to enter the standby sand storage tank by bypassing the structure. During the field inspection in the past two years，the structure was attacked by many typhoons，especially in the second half of 2020. The plan withstood the test，which proves that the design effect is good. In addition，the sand bypassing solution also saves investment costs. This study shows that properly shortening the sand barrier structure may also achieve the expected results，bringing new inspiration for similar beach nourishment projects.
