内容記述 | This paper presents the novel large-scale rainfall experimental facility, a pioneering development by the National Research Institute for Earth Science and Disaster Resilience (NIED). It delves into the intricacies of various large-scale slope failure experiments at this facility. These model experiments are unique in their approach, involving the attachment of multiple measuring instruments to a simple slope model. The standout feature of these experiments is the use of large-scale models, which facilitate easy handling of slope shaping, sensor placement, and application of realistic rainfalls, all tailored to the study’s objectives. The facility’s unparalleled ability to control all experimental parameters is a crucial advantage, enabling the realization of more realistic natural rainfall conditions and external forces. This unique feature makes the experiments invaluable, setting our research apart. However, establishing diverse simulation methods is essential to exploit this advantage fully. The methods will allow us to explore a broader range of scenarios and further benefit from these experiments.
