People live in limited areas which is usually located on alluvial soil in Taiwan. Severe damages on structures induced by soil liquefaction during some major earthquakes caused losses of people's lives and properties. Besides, the city development was gradually expanded to the mountain areas since the urban areas were highly developed. However, mountains in Taiwan are steep and with lots of joints. Landslide was frequently induced by earthquake and the traffic in mountain areas was interrupted. Food and material could not be delivered to the mountain area and it becomes a stumbling block in the emergency response system. This study is mainly to modify the module of liquefaction potential and develop the module of landslide. In the module of liquefaction potential, the geotechnical database will be constructed in TELES for predicting the liquefaction potential and settlements induced by liquefaction. In the module of landslide, the gradient of the slope can be calculated according to the digital topography model and the geological map. The landslide potential is classified as several categories in consideration of earthquake acceleration. The threshold of acceleration trigging landside for each category is defined. Mapping with the road map, the impact of landslide to the road in mountain area can be evaluated once the peak ground acceleration of the site is predicted by TELES. The analytical results from the modules of liquefaction potential and landslide potential could be a basic reference for emergency responses. |
