Geotechnical engineering landslide model test box

Abstract

The invention relates to a geotechnical engineering landslide model test box which overcomes the defects that the landslide model test wastes time and energy in the prior art. The geotechnical engineering landslide model test box comprises a box body, wherein the box body is basically a cuboid; an inclined plane is arranged on the inner sides of the two opposite side faces with the maximum areas of the cuboid; the inclined plane is perpendicular to the two side faces, and divides an inner space of the cuboid into an upper part and a lower part; and the shape of the inclined plane is similar to that of a slide face simulated by a geotechnical engineering landslide model test. According to the geotechnical engineering landslide model test box, the inclined plane is arranged in the test box, and divides the inner space of the box body into the upper part and the lower part, namely a part above the inclined plane and a part below the inclined plane; the shape of the inclined plane is similar to that of the slide face simulated by the geotechnical engineering landslide model test; when the geotechnical engineering landslide model test is performed, the part below the inclined plane does not need to be filled with a model material; and therefore, the filling quantity of the model material is reduced greatly, and manpower and financial resources are saved.

Description

technical field [0001] The invention relates to a geotechnical engineering landslide model test technology, in particular to a geotechnical engineering landslide model test box. Background technique [0002] Indoor similar model test is a commonly used research method for geotechnical slope engineering problems. Because the main parameters of the test object can be flexibly set according to the research needs, the dominant factors of the research problem are highlighted, and the size is smaller than the prototype to save manpower and material resources. It is a method that plays a pivotal role in slope engineering research. figure 1 In the shown slope structure, the slope 11 is generally divided into a sliding body 12 , a sliding surface 13 and a sliding bed 14 in engineering. During the sliding process of the slope 11, usually the sliding body 12 slides along the sliding surface 13, and the sliding bed 14 below the sliding surface 13 does not participate in sliding. In th...

Problems solved by technology

In fact, in the study of the instability and failure mechanism of slope engineering, in order to fully explain the problem, it often involves comparative analysis of multiple sets of sliding surface shapes. In this way, every time the sliding surface shape is changed, it is necessary to refill or adjust the sliding bed or even the entire sliding surface. model, which also results in a longer test cycle and increased test costs

Therefore, the similar model test of slope engineering in the prior art is time-consuming and laborious, especially when many groups of tests need to be carried out.
