Investigation of Apron Setting on the Main Deep Trough of River Bed by 2D Unsteady Flow Simulation

Abstract:

This study uses SMS-2D unsteady flow model to simulate apron setting and discuss its scour protection due to bow wave around the bridge pier on the main deep trough of 24-pier ChihShang Bridge and 3-pier Taitung Bridge in 100 years return flood peak flow, on the downstream BeiNan River in East-Taiwan as case study. Further, the topic of this study is to evaluate location-oriented scour likely result in accelerated erosion of critical piers by apron setting designed sizes in case of excessive cost, thus, providing reliable information and references for bridge engineers.
