Embodiment Construction

[0017] Such as Figure 1-3 As shown, the horizontal loading system of the present invention is composed of a reaction wall 1, a servo loading cylinder 5, a loading plate 6, a guide rod 4, and an anchor cable 2. The reaction wall is embedded in the foundation (the depth of the foundation is determined according to the relevant calculation results). Two anchor cables 2 are installed on the top for reinforcement, and multiple servo loading cylinders are installed on the ground part of the reaction wall. One end of the servo loading cylinder is connected to the loading plate, and there is a guide rod between the reaction wall and the loading plate. It is connected with the loading plate through a ball joint, and the servo loading cylinder is fixed by the servo loading cylinder support 3 .

[0018] The reaction wall is divided into a cantilever section above the ground and an embedded section of the underground part. The reaction wall is a reinforced concrete structure and provides...

Abstract

The invention discloses a roadbed slope retaining structural object large-scale model test loading system. The horizontal loading system is composed of a reaction wall, servo loading cylinders, loading plates, guide rods and anchor ropes. The reaction wall is embedded into a foundation, the two anchor ropes are arranged on the top of the reaction wall for reinforcement, the multiple servo loading cylinders are installed on the above-ground portion of the reaction wall, one end of each servo loading cylinder is connected with the corresponding loading plate, and the guide rods are arranged between the reaction wall and the loading plates. By means of horizontal loading, the magnitude of force transmitted to a structural object and the distribution mode of the force can be clearer. Gradation loading is achieved through a servo loading system, the real stress state of a soil body can be more accurately presented again, and more real experimental data can be conveniently obtained. The reaction wall is embedded into the soil body and reinforced by the anchor ropes, displacement is well controlled, the influence on the environment is small, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a loading system for a large-scale model test of a roadbed side slope retaining structure. Background technique [0002] The retaining structure is a powerful measure to ensure the stability of roadbed and railway embankment slopes, and it can resist deformation and failure modes, structures and geotechnical conditions of various slope retaining reinforcement structures such as sliding piles, retaining walls, anchor cable frames, and steel pipe grouting. The interaction mechanism and the actual performance research of different reinforcement methods have important engineering significance. However, due to the complexity of the interaction between rock and soil and structures, its stress mode and failure mechanism are often difficult to obtain breakthroughs through theoretical research, and model tests can be more effective. [0003] At present, in the large-scale model tests of retaining structures, the vertical load is us...
