Centrifuge Modeling on Capture Performance of Tilted Open-Type Sabo Dam
As open-type Sabo dam has gained prominence in recent decades, the role it plays in debris flow hazards has become more apparent. Vertical and tilted forms of open-type Sabo dam generated various consequences in the debris flow hazard of Nashizawa (Japan) in 2014, indicating that the impact of inclination needs deep exploration. To solve this problem, this study employs centrifuge tests, which are uncommon in the field of debris flow, to establish not only the feasibility of utilizing the centrifuge to reproduce debris flow hazards, but also to simulate the behavior of various open-type Sabo dams to catastrophes under the same conditions, aiming to make insights into the different performances through comparing the vertical type (0°) and the tilted type (20 and 40°) from the aspect of impulse derived from impact load, capture rate, and blockage area rate et al. The findings indicate that the vertical open-type Sabo dam has a high capture rate and low impulse during the hazards. On the other hand, the tilted open-type Sabo dam has a lower capture rate and a high risk of missing stones during climbing than the vertical one.
