Abstract

The invention provides a gradient pressurization experimental device and a gradient pressurization method, which belongs to the field of tunneling engineering. The gradient pressurization experimental device comprises a pressurization component and a tunnel model experimental device. The pressurization component comprises a spacing frame and a plurality of pressurization bags, wherein a plurality of accommodation spaces that are spaced from one another are formed in the spacing frame, and the pressurization bags are adapted to the accommodation spaces. A pressurization inlet is arranged on the pressurization bag and is used for inputting fluid into the pressurization bag, a hollow cavity is formed in the tunnel model experimental device, and the pressurization component is adapted to the side wall of the hollow cavity. The invention also provides a gradient pressurization method based on the gradient pressurization experimental device. The gradient pressurization experimental device and the gradient pressurization method provided by the invention can provide pressure with graded distribution to a stratigraphic model material and an underground structure model in an experiment, so as to be more close to practical situation and improve the reliability of experimental results.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a gradient pressurization experimental device and a gradient pressurization method. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. With the development of engineering equipment and technology, tunnels have become a very common architectural form. The development of tunnel-related technologies is inseparable from simulation experiments. In the simulation experiment, three principles of static effect equivalence, dynamic effect equivalence and boundary effect equivalence need to be met. [0003] The existing experimental methods for the tunnel model are limited by the structure of the existing experimental box, and cannot accuratel...
