    Abstract
    Prediction of landslide surge in reservoir lies in the calculation of sliding velocity. For the present, the application of formula commonly used for predicting sliding velocity in projects has been limited within a certain range in that both the complicated influencing factors and controling conditions are simplified. Based on the principles of discrete element method for calculating the rock velocity, the sliding velocities of landslide masses in various zones at different moments are acquiried by means of the statistical analysis. Taking the deformation and failure mechanism of certain reservoir slope in the upstream of the Yellow River as research object, the dynamic change process of sliding velocity under the potential condition of instability is analyzed and predicted through the discrete element method and the analysis and prediction of the surge height are carried out according to the velocity of landslide masses while sliding into water.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
