Due to the special geological background of formation of Taiwan, complex geological and topographical conditions, Taiwan is located in an area with extremely high crustal activity. Nature disasters continuously happen, including earthquakes, landslides, slump, debris flows, subsidence, etc. However, with the high density of population brings expansion of land usage, the geological disasters causing by land development has become a nightmare of Taiwan. Based on this reality, since the land use and the accompanying engineering process based on the living activities of the citizens cannot be banned entirely, only the high emphasis of the relationship between engineering process and geological disasters, systematic researches, development of new technologies can achieve the goal of avoiding and reduction of disasters. Because of the concept of disaster prevention is rising, the role of engineering geology is getting increasingly important day by day, such as flood control in mountain areas, management of catchment, urban disaster prevention (especially large-scale earthquake disasters), etc. All require the use of relevant knowledge of engineering geology. The critical research themes of this laboratory are to understand the mechanical and engineering characteristics of geological materials (including soil and rock) and apply them to disaster prevention. And we also continue to actively participate in related national disaster prevention research (especially hillside disaster prevention). Also, this laboratory supports applied geology research team to understand the characteristic of geomechanics as a purpose, focus on building and integrate the subjects between Earth Science system (emphasize on the training of geology) and Civil Engineering (emphasize on engineering), and take the application of practical engineering as a goal.
