Abstract
Tunneling in soft strata with mixed soil and rock is usually complicated and requires great efforts to maintain the stability of tunnel and excavation face, especially for the tunnel entrance sections. The upper part of a tunnel is generally covered with loose deposits while the lower part passes through weathered rock. The surrounding rock has very low strength and barely any stabilizing capacity. This chapter introduced how to use the underground engineering stable equilibrium theory and corresponding techniques to solve such a case.
