Abstract

During the excavation of connecting channel between the main tunnels using the mechanical shield method or pipe jacking method, the loading situation on the T-joint is very complicated. A vertical loaded full-scale steel-frame which can imitate the surrounding soil loading is invented to ascertain the action mechanism of each part. It can burden seven-ring segments and concern the soil spring effect. Prior to the field test, the entire installation of the facility is modelled, simulated and analysed to evaluate the safety of the construction. The analysis results show that the steel frame rotates seriously when the steel frame is not welded to the base. After welding the steel frame with the base, the rotation phenomenon of the steel frame can be effectively eliminated and the stress and displacement of each part are in line with the standard for design of steel structures.
