Quais são os métodos atuais de construção do túnel na China?
At present, the construction of railway and highway mountain tunnels in China mainly adopts the New Austrian Tunneling Method, with anchor spray support as the main means and secondary lining as a reserve, closely following the construction of the excavation face to the maximum extent, prioritizing the safety of the excavation face construction, and controlling the deformation of the surrounding rock before support to a limited extent, fully exerting the self stability of the surrounding rock, and preventing the As rochas circundantes de entrar em um estado solto . hastes de ancoragem desempenham um papel fundamental nesse processo . uma grande quantidade de experiência em engenharia e evidências experimentais mostraram que as hastes de ancoragem que requerem são melhores efeitos de suporte que não são mais protetidos que não protestam ou não são de manutenção e as características de ação que não são mais protetidas e a ancoragem não protestam e a ancoragem não protestam que não protestam. time, which is not conducive to the rapid construction of tunnels and the reinforcement and stability of surrounding rocks, affecting construction safety. In addition, with the rapid development of China's railways and highways, the construction areas continue to expand towards the western plateau and southern mountainous areas. The geological conditions encountered in engineering construction are becoming increasingly complex and varied, and the design theory is shifting from Suporte passivo ao suporte ativo . A engenharia do túnel possui requisitos cada vez mais rigorosos para o suporte à haste da âncora, especialmente em termos de pontualidade .
