Since the material of the landslide dam has not been manually sorted, there is a large spatial variability. The empirical creep model widely used in artificial rockfill dams, which has problems such as complex formulas, too many parameters and no clear physical meaning, it is difficult to be directly applied to the long-term deformation calculation of the landslide dam. Through the analysis of the relationship between strain energy and stress state in the creep process, combined with the exponential function relationship between strain energy and time and the creep stress dilatancy relationship, a new creep model of coarse-grained soil is proposed. The proposed creep model can comprehensively consider the strain and stress quantities during creeping, and has the advantages of fewer model parameters and clear physical meaning of parameters and wide applicability. The proposed creep model is based on the initial strain method for creep numerical calculation, and the long-term deformation calculation of the spatial variability distribution of creep pa-rameters was carried out for the Hongshiyan landslide dam. The calculation results show that the deformation calculation results considering the spatial variability of creep parameters are more consistent with the monitoring results. creep model strain energy coarse grained soil landslide dam spatial variability Full Text Cite Share Download PDF Status: Published Journal Publication published 10 Jul, 2025 Read the published version in Natural Hazards → Version 1 posted Reviewers agreed at journal 03 Sep, 2024 Reviewers invited by journal 20 Jul, 2024 Editor invited by journal 19 Jul, 2024 Editor assigned by journal 13 Jul, 2024 First submitted to journal 13 Jul, 2024 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
