Field Tests and Numerical Analysis of Anti-Buoyancy Anchors

With the development of urban construction, the utilization of underground spaces becomes more and more popular, and the buoyance concerns of underground buildings and structures becomes increasing urgent. Especially in areas with high groundwater level, the impact of antifloating stability on the structural safety is also increasingly prominent. In this paper, the mechanism and failure modes of antifloating anchors are evaluated. The mechanical and deformation characteristics of antifloating anchors are discussed by field tests and the threedimensional finite element model throughout commercial software ABAQUS. The mechanism of the antifloating anchor is revealed, and practical conclusions are also provided in the paper.

Abstract

Abstract: With the development of urban construction, the utilization of underground spaces becomes more and more popular, and the buoyance concerns of underground buildings and structures becomes increasing urgent. Especially in areas with high groundwater level, the impact of antifloating stability on the structural safety is also increasingly prominent. In this paper, the mechanism and failure modes of antifloating anchors are evaluated. The mechanical and deformation characteristics of antifloating anchors are discussed by field tests and the threedimensional finite element model throughout commercial software ABAQUS. The mechanism of the antifloating anchor is revealed, and practical conclusions are also provided in the paper.
