Highway Rockfall Measurements Using LIDAR

This project plans to advance our measurement technologies of rockfall on 1 or moreclocal highway rock cuts using the laser radar (LIDAR) techniques that have developed. Previous research has shown a tentative relationship between rockfall and rainfall. This time used on installing nested piezometers to measure groundwater pressures behind the rock face so that the Principal Investigator (PI) can correlate not only rainfall and freeze-thaw cycles with the rock fall quantities, but also the cumulate buildup of water pressure behind the face. As a result the project hopes to be able to determine why some rainfalls cause rockfalls while others do not. Anticipated benefits include the advancement of a modeling capability, as well as some insight as to whether installing passive drainage in highway rock cuts would serve to decrease rockfall.
