Landslide Prevention and Mitigation for Road in Humid Tropical Region
The landslide phenomenon is considered as a natural disaster directly affected the development of mountainous areas in general to the traffic and transportation sector particularly.From the damages of typical landslides in Vietnam, such as on Highway No.37 (at Chen Pass), Son La Province, the Nam Non Bridge on the Western Route, Nghe An Province, at Hai Van Pass Station, on Highway No.6 and along the Ho Chi Minh Route in the Central, it is able to be recognized that the responding in face to this dangerous phenomenon seems to be quite passive.This paper proposed a new plan proactively to prevent and mitigate the occurrence of this natural disaster for the new design and management of roads through mountainous terrain areas.The core of the new plan is to build up a landslide risk assessment map (LRAM)by the combination of the inventory map based on methods of collect historical data, field surveys, interpretation of aerial photos and the landslide susceptibility map which are analysed from landslide manifestation in study area and landslide causative factors, such as topography, geomorphology, geology, climate and human impact as a basis for predicting the future.For landslide susceptibility map, methods of analytical hierarchical process approach or fuzzy relation are applied.This proposed map indicates boundary, active status of each landslide as well as the susceptibility of each coordination to landslide that is fully effective for landslide prevention and mitigation of hilly and mountainous areas with humid tropical climate, including Vietnam.
