An important part of a flexible net rockfall catchment fence system is the foundation. Catchment systems have been growing in capacity, able to stop larger and higher energy rockfall events. The trend for foundations has been for them to become larger and more rigid, according to the Association of Geohazard Professionals (AGHP). Members of the AGHP are interested in feedback from owners and engineers experienced in foundation design and their performance in order to synthesize an empirical study of catchment fence foundations and their design. More details can be found at the link below.
The rock at left travelled nearly a mile down the slope and picked up some significant velocity before impacting a house, hitting the back wall and damaging the ceiling before dropping through the floor into the garage and damaging the garage door. In an often-overlook advantage of the current financial crisis, the house was currently in foreclosure and therefore not occupied at the time of the damage.

This fall, TRB will release Rockfall: Characterization and Control, which will address rockfall hazard identification and evaluation, investigation process, mitigation options, and maintenance and management programs. The 400 page publication will include a DVD with […]
