Developing and Calibrating Fragmental Rockfall Models using Physics Engines
| 项目名称： | Developing and Calibrating Fragmental Rockfall Models using Physics Engines |
| 摘要： | The objectives of the research work are to: (1) Develop a field data collection methodology to observe rockfall events, generated by scaling projects. Develop a detailed database of rockfall events, collected and analyzed from DOT rock slope scaling projects, and utilize this database to define ranges of input parameters needed to simulate rockfalls. (2) Build a user interface with the selected physics engine to permit model self-calibration based on observations, and generate numerous simulations providing probabilistic output data. Define and produce useable metrics such as runout distance for a defined % of the volume, bounce height and energy etc. (3) Determine the basis for decisions related to goodness of fit of simulations, and simulate many known rockfall events to define appropriate ranges of input parameters to generate realistic fragmental rockfall models for different geological settings and slope condition states. (4) Simulate the interaction between falling fragments and the underlying slope, considering geology, geometry and whether the blocks will be impacting outcropping rock, talus, soil, and possibly vegetation, to refine the fragmentation model. |
