A Quasi-periodic Approximation Based Model Reduction for Limit Analysis of Micropile Groups,d is made capable of solving the numerical static limit analysis problem of soil reinforced by a group of micropiles according to a 2D plane strain model. The method has been successfully applied to the limit analysis problem of a soil reinforced by a large group of micropiles when resources did not permit solution of the full model.作者: observatory 時間: 2025-3-22 20:25 作者: 豐滿中國 時間: 2025-3-22 23:07
