| 總結: | Rockfall refers to naturally occurring hazards when chunks or blocks of rock debris dislodge from height. Such events pose harm to the surroundings such as endanger human or animal life and also causes economic losses. Since the late twentieth century, many countries have come up with various ways to rate potential locations with such occurrences. These methods refer to Rockfall Hazard Rating Systems (RHRS).
This project aims to build a new and improved RHRS by expanding on the current systems, by introducing concepts of risk management and system safety. Throughout the entire length of the project, current RHRSs, especially Oregon’s system will be further analysed to identify the more critical parameters. Furthermore, as current RHRSs do not identify with parameters are actually consequence factors and which are probability factors, this project will be separating the two categories to let the user have a clearer view of the system. This eliminates the remaining factors that are less commonly regarded in reports and gives the new RHRS a cleaner and more presentable look.
Also, a new component which is a Weight system will be introduced into the project’s new RHRS. Current systems do not come with in-built weighting systems and thus may not be very accurate when comparing different locations. This is because different locations are affected by different factors by varying degrees.
The author hopes the new system proposed in this project will serve to better help organisations not only in Singapore, but also around the world when doing assessment of rockfall hazards, and also aid any further studies pertaining to rockfall hazards. |
