The curve of landslide thrust plays a key role in landslide design.The commonly used transfer coefficient method(TCM)and Morgenstern-Price method(MPM)are analyzed.TCM does not take into account the moment balance between slices.Although MPM considers the moment bal-ance,the calculation is complex,and it does not consider that the force between slices may be less than zero at the back edge of the landslide.The rationality and feasibility of the improved MPM are verified by calculating the landslide stability coefficient and landslide thrust at different reservoir water levels.This paper studies the law of landslide thrust when the reservoir water level changes,and discusses the determination of design thrust,to provide a certain theoretical basis for the design of reservoir land-slides.
