Abstract

The invention discloses an underground engineering three-way loading test device which comprises a fixed frame, a movable skip car, loading devices, a traction system and a hydraulic system. The vertical loading device is arranged on the upper portion of the fixed frame, and loading in the first direction from top to bottom is achieved; the loading device is arranged on the left side of the movable skip car, so that loading in the second direction from the left to the right is realized; the loading device is arranged on the right side of the movable skip car, so that loading in the third direction from the right side to the left side is achieved, wherein the second loading direction is right opposite to the third loading direction and is perpendicular to the first vertical loading direction; and the traction system is arranged on the lower portion of the movable skip car, so that the movable skip car can be moved into or out of the fixed frame; and the hydraulic system provides pressure load for the loading devices. The invention further discloses a loading test method of the test device. By adopting the device and the method, the stress of the test model can be more practical, thetest process is more convenient and faster, and the test cost is lower.

Description

technical field [0001] The invention relates to the field of geotechnical engineering model tests, in particular to a three-way loading test device and a loading test method for underground engineering. Background technique [0002] With the continuous advancement of underground engineering represented by tunnels in our country, how to evaluate the design quality of underground tunnel engineering and how to ensure the rationality of engineering structure design is an increasingly challenging problem; its research involves geotechnical engineering , structural engineering, seepage and vibration and other mechanical fields, the impact of traffic load on engineering is also very significant. [0003] At present, there is a lack of practical and effective analysis methods at home and abroad, mainly relying on engineering experience for estimation, which has great blindness; in order to make up for the limitations of theoretical analysis and verify the rationality of theoretical ...
