摘要：Based on the PECK formula, the two-dimensional settlement calculation of the stratum under the tunnel excavation is extended to three-dimension, and the three-dimensional solution of the ground settlement under the influence of the superposition of the tunnel excavation of each section under the double-line tunnel variable section excavation is analyzed and analyzed. It shows that under the action of superimposed disturbance of double-line construction, the settlement of the ground surface mainly shows displacement to the tunnel excavation, and the settlement of the ground appears settlement valley directly below the excavation axis of the double-line tunnel; the building structure has a significant effect on the settlement of the surface and the effective rigidity The larger, the wider and shallower the settlement trough. At the transition of excavation, the surface settlement is prone to "points".
