Abstract
This study investigates the effect of cylindrical baffle arrays behind a rigid barrier on debris flow behavior and dynamic impact load. Small-scale tests were performed with various transverse blockage ratios and row numbers of baffles. High-speed cameras were installed at the flume's top and side, and load cells were installed in front of the rigid barrier. Moreover, glass beads simulated large boulders with debris flow in the flume. Test results revealed that the impact load of debris flow on the rigid barrier was significantly reduced using the cylindrical baffles behind the rigid barrier. In addition, the increased transverse blockage ratio of baffle arrays led to a greater impact load of debris flow because of flow suppression due to the baffle arrays.
