Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 As shown, a device for simulating a bending bridge test includes a soil box, an MTS loader, and an abutment. Two transverse steel plates are arranged symmetrically in the left and right sides of the soil box, and the transverse steel plates are connected to the inner wall of the soil box. The soil box The interior is filled with sand, the lower end of the horizontal steel plate is inserted into the sand, a vertical channel is formed between the two horizontal steel plates and the upper surface of the soil, the abutment is placed in the vertical channel, and there is a gap between the abutment and the horizontal steel plate. To prevent scratching between the abutment and the transverse steel plate during the test, the EPS plate is pasted on the rear side of the transverse steel plate, and the EPS plate is pressed against ...

Abstract
The invention relates to a curved bridge simulation test device. The device comprises a soil box, MTS loaders and an abutment, wherein two transverse steel plates are arranged in bilateral symmetry inthe soil box, the transverse steel plates are connected with inner side walls of the soil box, the soil box is filled with sandy soil, the lower end of each transverse steel plate is inserted into the sandy soil, a vertical passageway is defined by the two transverse steel plates and the upper surface of a soil body, the abutment is arranged in the vertical passageway, a gap exits between the abutment and each transverse steel plate, an EPS plate is installed on the rear side faces of the transverse steel plates, the EPS plate abut against the abutment to block the gaps, the space formed by the rear sides of the transverse steel plates and the soil box is filled up with sandy soil, the sandy soil in the space is flush with the top face of the abutment, the right side face on the upper portion of the abutment is connected with one transverse MTS loader, and the front side face on the upper portion of the abutment is connected with one longitudinal MTS loader. In the using process, bidirectional loading is performed on the abutment through the two MTS loaders to make the abutment move along a path with determined curvature, and the actual location changing process of a curved bridgeis simulated.
Description
technical field [0001] The invention relates to a device and an experimental method for simulating a bending bridge test. Background technique [0002] With the rapid development of my country's economic construction, both urban road traffic and expressway construction have achieved great development. However, due to the complex geological structure in China, the bridges in highway construction are in the design, construction, or detailed construction. The complexities are unprecedented, but for the entire bridge construction, the most difficult problem for designers is the interaction between the beam structure and the soil. [0003] As we all know, the interaction between seamless bridge and soil is an unresolved problem in the world today. Among them, the quasi-static test between seamless curved bridge and soil has not been carried out related indoor model tests at home and abroad due to the difficulty of loading. As Chinese scientific research and engineering personnel ...
