Based on the Foshan-Dongguan Intercity Line Changlong Tunnel Project. indoor tests and numerical simulations were conducted to study the instability and progressive failure process of the cutter replacement ground at atmospheric pressure. The fast Lagrangian analysis of continua method was adopted to establish the numerical model. The safety factor of the cutter replacement ground was... https://parisnaturalfoodes.shop/product-category/toothpaste-mint-free/
