Study on Effect of Frame Structures Crossed by Shallow-Buried and Mining Tunnelling

Abstract:

During the shallow-buried tunnel excavation, the formation will be affected and the nearby buildings will be caused fracture. By using three dimensional software MIDAS/GTS, the interactions among structures-soil-tunnel system is considered in this paper, and the working condition of shallow-buried underground excavation is simulated in the independent foundation of frame structures. It is indicated that building will tilt to the side of tunnel as the horizontal distance L between building and tunnels is increasing, after reaching certain distance, the influence to the building tends to little, at the same time, the maximum first principal stress P₁ and maximum deformation rate E₁ show a trend of decrease. When the kind of soil is worse, the settlement and non-uniform settlement of buildings increase, meanwhile P₁ and E₁ increase. With the increasing story of the framework, the settlement of building is nearly not affected, and P₁ and E₁ decrease slightly.
