After the test, the following conclusions by the finished truss spherical sliding bearing, these two types of hinge withstand pulses and pulse load combined with the design of the corner box ah, by rotation of the test made after shear test, which is similar to the case of the slide bearing hinges can be seen in the concrete surface manholes along the crack spalling, and in the steel hinges do not see this phenomenon proves steel played a role. Hinge sliding bearing is free to rotate in any direction. Sliding bearings and "existing hinge different" because of the neck is not easy even sliding concrete spherical bearing, so its function is less than to the good of finished steel ball bearing slide elasticity, which shows the pulse loads, steel hinge for stable than concrete hinges, in different directions so the hinge to note concrete vibrating compaction. According to the test of experience in Germany, hinge reinforcement shall be arranged in accordance with the test and the test results photoelastic model full-scale concrete hinges, hinge on the concrete proposal is designed primarily through the midpoint of the hinge reinforcement arranged to account for 40% of steel, slide The remaining 60% of the bearing steel is arranged along the longitudinal direction. Since the hinge angle resistance, anti-torque generated by the angle of rotation torque hinge at the center of the west, as the vertical force on the hinge. N force in the role of refined seismic sliding spherical bearings, hinges concrete in tension will produce a crack. Development of sliding bearings, the successful solution of the rubber molding method within the bearing plate hole as a sliding bearing function, generally require bearing load and live load has a constant vertical force and other functions supporting the upper structure, but also to adapt to temperature changes, sliding bearing concrete shrinkage and other produce rotational displacement horizontal displacement function, adaptation caused by the live load deflection and torsion beam generated by rotational displacement of the load bearing function of circuit design and load support performance and test methods seat by actual testing of Guangzhou-Shenzhen high-speed railway stone quasi Trond other projects can be summarized in the following conclusions. Bearing by measuring the force calibration and field tests showed that the formation of the next board in the oil pressure control, the injection of special hydraulic oil from the oil pressure reflect changes in the actual reaction force bearing method is very rational and efficient use, the sliding supporting Force measurement accuracy seat holder carrying capacity up to 1%, since the superstructure load bearing reaction force size by concrete shrinkage and creep, the combined effects of the voice in the loss, and other factors, sliding bearings in a stage for support reaction force caused by certain factors can be tested indirectly understand the factors that impact on the structure of the future is expected on the basis of the load bearing study, further research using the sliding seat to adjust the seat structure of the anti- force.
