Abstract

The invention relates to a hidden water body or water filling karst pipe system in a similar model test, comprising a test stand frame. The test stand frame is internally paved with a plurality of layers of similar materials; tunnels are tunneled in the similar materials; the similar materials are internally provided with a hidden water body or a water filling karst pipe; the hidden water body or water filling karst pipe is connected with a pressure pump at the external part of the test stand by a water inlet pipe and water outlet pipe; and the pressure pump is connected with a control device. Simultaneously, the invention also discloses an embedding method of the system. The invention researches the hidden water body or water filling karst pipe system in the similar model test and the embedding method thereof, and solves the problem for embedding and simulating the hidden water body or water filling karst pipe. Compared with the research of former researchers, the hidden water body or water filling karst pipe is embedded into the similar materials of the model test., thereby being more near engineering practice and an obtained water burst theoretical research result have a wider application range.

Description

technical field [0001] The invention relates to the field of geomechanics, in particular to a concealed water body or water-filled karst pipeline system and an embedding method in a similar model test. Background technique [0002] my country's karst area is widely distributed. Building underground tunnels or excavating roadways in karst areas can easily induce large-scale and sudden water inrush disasters during construction. Scholars in my country have carried out a lot of water inrush research work, but there are also obvious weaknesses. When doing the basic model of water inrush test, uniform materials are generally used, and rock and soil layers are laid simplified. In actual engineering, affected by factors such as geological structure and dissolution, there are often many unfavorable geological bodies in engineering rock and soil, such as hidden water bodies or water-filled karst pipelines. Contents of the invention [0003] The purpose of the present invention is ...
