Emergency Roadworks and Suggestions to Improve the Occupational Safety after the Ji-Ji Earthquake

It is found that most road damages triggered by the Ji-Ji earthquake occurred in the Taichung City, the Taichung County, and the Nantou County. The main causes for these road damages are landslides and rockfalls. Therefore, in the emergency roadwork to repair these roads it is not only necessary to remove the debris that blocked the roads but also necessary to stabilize the roadside slopes to prevent further collapses. This article studies the current conditions in emergency roadworks and investigates the reasons of slope failures. It is hoped that this study will help the roadwork crew to quickly finish the repairs and increase their awareness of dangerous slopes to protect their own safety.
