Background
With the investment of a large amount of funds in China, infrastructure construction such as traffic and the like, particularly railway construction is carried out; however, the development of railways inevitably has the problem of tunnel construction, and due to the characteristics of complex terrain and variable geology in China, the tunnel construction faces a new problem of endless development; for example, many mountains in the southwest area of China inevitably encounter soft rock along with the construction of tunnels. Soft rock generally refers to rock mass with weak rock quality, low bearing capacity, joint crack development and broken structure; if the tunnel cannot be properly treated when passing through weak surrounding rocks, the tunnel is very easy to have large risks of deformation, collapse and the like; once the danger occurs, not only the construction safety is seriously influenced, but also the construction progress is influenced by high cost and high difficulty in treatment, thereby bringing great difficulty to engineering construction.
