A device for enhancing abutment-soil interaction and its implementation method

Abstract

The invention relates to the fields such as geotechnical engineering, bridge engineering and the like, in particular to an apparatus for improving an interaction of a bridge abutment-soil body and animplementation method thereof. The apparatus comprises a steel box for filling sandy soil, wherein two inner side walls of the steel box are respectively and vertically provided with a transverse steel plate, a vertical clamping groove is formed between the two transverse steel plates, the front side and the rear side of the lower end of the vertical clamping groove are respectively provided witha channel steel with two side ends being respectively connected with the corresponding transverse steel plates, the upper side of the two channel steel is fixedly provided with a horizontal steel plate which is longitudinally arranged, and the upper side of the horizontal steel plate is provided with a polytetrafluoroethylene plate for placing a structure. The apparatus for improving the interaction of the bridge abutment-soil body is not only simple in structure, but also capable of actually reflecting the response of the structure and soil body under an external effect, and can improve the test precision, and is also simple and convenient in implementation way.

Description

technical field [0001] The invention relates to the fields of geotechnical engineering, bridge engineering and the like, in particular to a device for enhancing the interaction between abutment and soil and an implementation method thereof. Background technique [0002] With the continuous advancement of my country's modernization drive, the civil engineering industry has also developed vigorously. The construction and design of many projects need to be supported by sufficient scientific research and theoretical foundations, especially in the fields of basic engineering and coastal engineering. my country's colleges and universities continue to give full play to their own advantages in talent and technology, and continue to contribute to my country's infrastructure construction. In the field of civil engineering, due to the complexity of the soil itself, it is particularly important to study the response between components and soil. [0003] At present, for the interaction ...

AI Technical Summary

Problems solved by technology

In actual engineering, many structures are in direct contact with the soil. However, in related tests, due to the consideration of test safety and the complexity of actual operation, etc.

Does not truly simulate the interaction between structures and soil

For example, when we traditionally consider the response of the abutment to the temperature effect, we place the model abutment directly on the sand or on a large flat cushion for related tests. When the structure is directly placed on the sand for the test, It is easy to cause the structure to slip due to its own gravity, and on the other hand, there are certain safety hazards

When the abutment is directly placed on a large flat cushion for related experiments, since the bottom of the structure basically slides on the cushion, on the one hand the surface of the cushion may be difficult to slide due to the excessive friction coefficient, on the other hand Since structures in actual engineering are often in direct contact with sand and soil, if a large area of ​​cushion is used to support the structure in the test for slip tests, it often cannot truly reflect the actual situation, resulting in excessive test errors
