Problems solved by technology
Because the model test takes a long time and is expensive, if the horizontal tunnel and the tunnel are made into rigid components, it cannot be carried out under various combination conditions (the angle between the tunnel axis and the horizontal tunnel axis is different; the height difference between the left and right tunnels) different tunnel inclination angles; the distance between the left and right lines, that is, the length of the transverse tunnel is different), which restricts the development of related model tests

The invention relates to a device and a method for simulating three-dimensional rotations of a cross hole in a double-track tunnel model test. The device comprises a cross hole simulation system, wherein the upper part of the cross hole simulation system is provided with a tubular level, two ends of the cross hole simulation system are connected with tunnels through a hinged connection device, and the hinged connection device is provided with a compass. The device provided by the invention has the beneficial effects that the cross hole simulation system is detachable, and model tests can be conducted under the condition that the distance between a left tunnel and a right tunnel is different, that is, the length of the cross hole is different. The design of the hinged connection device can meet requirements that the cross hole is bent in the horizontal direction and the vertical direction and rotates in the model test, and the device is enabled to simulate model tests under various combined conditions.
Description
technical field [0001] The invention belongs to the field of similar model tests, in particular to a device and method for simulating three-dimensional rotation of a transverse tunnel in a model test of a double-track tunnel. Background technique [0002] The underground engineering model test is to reduce the actual engineering into a model according to a certain proportion according to the similarity ratio and the similarity theory, and to obtain relevant data and check design defects by performing corresponding tests on the scaled down or proportional model, which has become the field of underground engineering. As one of the most important research methods, many scholars at home and abroad have carried out a large number of model test studies on related issues such as tunnel ventilation, surrounding rock stability, and water inrush disasters. However, in the past, most of the research objects of model tests were single-line tunnels, and there were few researches on model...
