[0032]Example: Aiming at a certain subway engineering section, the shield tunnel structure of this section is in a fully-strongly weathered rock formation, and then there is a silt layer above. Andesite porphyrite, the lower part is strongly weathered andesite porphyrite. The ground conditions within the tunnel area are complicated because the main road with a large traffic volume is laid along the direction of tunnel excavation; on the left side of the excavation direction is a high-end residential area with a horizontal distance of 2m; The bonding is consolidated in the soil bin by high temperature to form a mud cake. Due to the complex ground conditions, there are no conditions for opening the bin. At the same time, this tender section is the track-laying base of the whole line. If the shield section of this section cannot be completed on schedule, the construction period of the whole line will be affected. The deadlines are under enormous pressure. After research, the shi...
