Abstract

Ring-beam supporting technology is increasingly used in coastal soft soil area. Based on a foundation pit supporting case of general hospital in Tianjin, the 3-dim finite element construction was simulated with MIDAS/GTS. According to the calculation, the stress and deformation characteristics of deep foundation pit supporting structure under the ring-beam action in soft soil area, and the surrounding soil settlement is analyzed. The final foundation pit supporting solution is selected between two different schemes. The analysis method and conclusions are useful for design and construction of other similar projects.
