摘 要：Landslides are serious geohazards that occur under a variety of climatic conditions and can cause many casualties and significant economic *** modelling,as a representative type of physical modelling,provides a realistic simulation of the stress level in a small-scale model and has been applied over the last 50 years to develop a better understanding of *** recent developments in this technology,the application of centrifuge modelling in landslide science has significantly ***,we present an overview of physical models that can capture landslide processes during centrifuge *** review focuses on(i)the experimental principles and considerations,(ii)landslide models subjected to various triggering factors,including centrifugal acceleration,rainfall,earthquakes,water level changes,thawing permafrost,excavation,external loading and miscellaneous conditions,and(iii)different methods for mitigating landslides modelled in centrifuge,such as the application of nails,piles,geotextiles,vegetation,*** behaviors of all the centrifuge models are discussed,with emphasis on the deformation and failure mechanisms and experimental *** on this review,we provide a best-practice methodology for preparing a centrifuge landslide test and propose further efforts in terms of the seven aspects of model materials,testing design and equipment,measurement methods,scaling laws,full-scale test applications,landslide early warning,and 3D modelling to better understand the complex behaviour of landslides.
