Problems solved by technology

[0005] Chinese patent CN202033951U provides a geotechnical engineering physical simulation testing machine, which adopts a steel frame structure placed on the ground, which can be used for geomechanical model tests on caverns and cavern slopes, but can only test the top, bottom, left, and right sides of the model. Loading in one direction, the model cannot be loaded in true triaxial
Moreover, the test machine is placed on the ground, and the scale is small, so it cannot be used for large-scale physical model tests.
[0006] Chinese patent CN100535267C provides a kind of foundation and slope engineering model test platform, the model box of the test platform announced by this patent is placed on the surrounding closed steel structure on the ground, although large-scale model tests can be carried out, but only for the model Loading at the top and cannot be used for physical model tests of excavation works such as tunnels and subway stations

Abstract

Provided is a loading device for a geotechnical engineering large-sized three-dimensional comprehensive simulation test bed. The loading device for the geotechnical engineering large-sized three-dimensional comprehensive simulation test bed comprises reaction walls and reaction beams, wherein the reaction walls are made of reinforced concrete, and are of a double-layer structure, a personnel operation channel is arranged between the double-layer reaction walls, a control pipeline penetrates into the position between the double-layer reaction walls through reserved horizontal installing holes formed in the reaction walls, and is connected to a control room of a ground test building, and the reaction beams stretch across the geotechnical engineering large-sized three-dimensional comprehensive simulation test bed, are arranged on the upper end faces of the reaction walls, and are fixedly connected with the reaction walls. The loading device for the geotechnical engineering large-sized three-dimensional comprehensive simulation test bed can achieve real three-dimensional loading, and can be used for simulation of geotechnical tests with different functions, such as an underground space and an excavation simulation test of the underground space, a foundation and slope engineering simulation test under the conditions of rain and rise and fall of the underground water level, a dynamic response test of a pile foundation and soil around a pile, a duct piece simulation test and a structural component performance test.

Description

technical field [0001] The invention relates to a physical model test device which can be used in geotechnical engineering such as tunnels and subway stations, foundation engineering, slope engineering, retaining structures, etc., especially a test platform which can carry out three-dimensional comprehensive simulation tests on large-scale geological models. In particular, it relates to a loading device used for a large-scale three-dimensional comprehensive simulation test bench of geotechnical engineering. Background technique [0002] Physical model test is an important means to study large-scale geotechnical engineering problems. It is widely used at home and abroad, and plays an important role in engineering research and design. Scholars at home and abroad have carried out fruitful research work on engineering issues such as the stability of the surrounding rock of the roof of the large mine, the stability of the rock mass of the dam body and the dam foundation, the stab...
