A method for establishing a dam body model capable of controlling the soaking line

Abstract

The invention discloses a dam body model establishment method capable of controlling a seepage line. The method is used to study stability and deformation of a tailings pond dam body, an earth and rockfill dam, and a slope. The method comprises the following steps: a, determining the shape and position of a seepage line of a dam body model, dividing the seepage line into a plurality of large segments; b, determining related parameters of critical control points; c, solving the position of a theoretical impervious layer; d, calculating position data of a relative impervious layer; e, using a same method to calculate related data of other large segments; f, and establishing a dam body model and laying the relative impervious layer. The method can control the shape and distribution characteristics of the seepage line in a model experiment, and improves similarity of a dam body model in an experiment and a practical dam body, so as to improve accuracy of the experiment.

Description

technical field [0001] The invention relates to a method for establishing a dam body model, in particular to a method for studying the stability and deformation of a tailings reservoir dam body, an earth-rock dam and a side slope. Background technique [0002] In the experiments on the stability and deformation of tailings dams, earth-rock dams and slopes, when there is seepage water in the dam body, the depth of seepage water, that is, the position of the infiltration line, has a great influence on the deformation and instability of the dam slope. The impact is significant. In traditional experiments, it is often only possible to control the ground water level, and cannot directly control the position and shape of the seepage water infiltration line. [0003] At present, in the model tests with underground seepage water, there are generally no measures how to control the location of underground seepage water, especially for the position of the infiltration line in dam slope...

Problems solved by technology

[0002] In the experiments on the stability and deformation of tailings dams, earth-rock dams and slopes, when there is seepage water in the dam body, the depth of seepage water, that is, the position of the infiltration line, has a great influence on the deformation and instability of the dam slope. Significant impact. In traditional tests, it is often only possible to control the ground water level, and cannot directly control the position and shape of the seepage water infiltration line accurately.

[0003] At present, in the model tests with underground seepage water, there are generally no measures how to control the location of underground seepage water, especially for the position of the infiltration line in dam slopes such as tailings dams, earth dams, and slopes. The groundwater level is different in different parts of the dam slope, and the seepage line is a curve, which is difficult to control accurately

The wetting line is mainly affected by the water level at the bottom, and it is also affected by the water level on the ground. The traditional method is to indirectly control the wetting line by changing the water level on the ground. This method is difficult to control accurately
