face. What’s more, the large knife plate installed in the front cuts the surface mud film of the soil and mixes with the mud and water to form the high-density mud, which is transported to the ground... high. Especially, when the pressure of the excavation bin is 0.2 MPa, the construction cost of the shield machine is effectively controlled. On the other hand, it not only reduces the deformation......

by researchers in the Soviet Union in 1950. A sliding mode control (SMC) differs from a simple relay controller because it relies on high-speed switching of control values and can be changed..., its control signal is discontinuous and produces adverse chattering phenomena [28] that may stimulate the high- frequency dynamics of system and, in the worst case, cause system instability......
is an underground two-story station with a main length of 180 m and was constructed via island-type excavation. The maximum excavation dimensions of the station tunnel are 22.16 m wide and 19.21 m high... and -7.335 MPa, respectively). Each tunnel is subjected to high compressive stress at the inverted arch, and because of the triangular layout of the tunnel, the arch waist of the running tunnels......
