Abstract : A large number of landslides and collapses are often triggered by earthquake, but little attention has been paid to the risk assessment of glacier lake outburst under coaction of earthquake and ice avalanches. To investigate the characteristic of hydrodynamic pressures under coaction of earthquake and ice avalanches, experimental analysis of hydrodynamic pressures were conducted under separate earthquake action and ice avalanches action, respectively. The ice block sliding into the reservoir was

Abstract : Echo state network (ESN) is an important method for time series prediction. However, the overfitting problem is likely to occur when the training data contain noise or outliers. To solve this problem, an ESN model based on smoothly clipped absolute deviation (SCAD) penalty function was proposed in this paper. Different from the traditional methods, such as ridge regression, L1 norm penalty, wavelet denoising and other methods added into the ESN model, the SCAD penalty function was used to select
