Finite-element Stress and Deformation Analysis of a Geomembrane Face Rockfill Dam
Published 2022-01-01“…For a certain reservoir dam that is a geomembrane face rockfill dam,the composite geomembrane is used as the face slab on the dam surface to prevent seepage.A three-dimensional nonlinear finite-element model of this reservoir dam was built to simulate the dam filling construction,the laying of the composite geomembrane,and the process of reservoir impoundment.The stress and deformation of the dam body and the composite geomembrane during the completion and impoundment periods were analyzed,and the rationality of the structural design of this geomembrane face rockfill dam was demonstrated.The calculation results show that the distribution of the dam body displacement and stress before and after impoundment follows the general rules and that impoundment is beneficial to the safety of the dam.Moreover,the shear failure of the dam body is prevented.The composite geomembrane is subject to tensile strain and stress in the lower half of the face slab due to boundary constraints.Nevertheless,the lateral and longitudinal safety factors calculated meet the requirements of design specifications,and the safety of the geomembrane is guaranteed.…”

A dual speech encryption algorithm based on improved Henon mapping and hyperchaotic
Published 2021-12-01“…Aiming at the problems of small key space, poor security, low encryption efficiency, and the inability to realize the trade-off between key complexity and encryption efficiency of existing speech chaotic encryption algorithms, a dual speech encryption algorithm based on improved Henon mapping and hyperchaotic was proposed.Firstly, the traditional Henon mapping was improved by extending the control parameter range and taking the nonlinear trigonometric function as the input parameter variable, which made the Henon mapping have larger chaotic space and higher chaotic complexity.Secondly, the improved Henon mapping was used to generate pseudorandom sequence, and the speech data was encrypted single time without repeated scrambling to obtain the first time encryption results of the speech data.Finally, Lorenz hyperchaotic system was adopted to encrypt the speech data after the first time encryption by Arnold secondary scrambling encryption and XOR diffusion encryption to obtaining the final ciphertext speech data.The experimental results show that, compared with the existing methods, the proposed algorithm have larger key space, higher encryption efficiency, and stronger robustness against various cryptographic attacks.…”
