Abstract

The invention discloses a model for researching jointed rock slope, and a manufacturing method of the model. The cross section of the model is a hexagon, the top surface, the bottom surface of the slope and the bottom surface are parallel to each other, the slope exists between the top surface and the bottom surface of the slope, the variation range of the side slope tilt angle is 30-75 degrees, the side face between the top surface and the bottom surface is perpendicular to the top surface and the bottom surface respectively, and the side face between the bottom surface of the slope and the bottom surface is perpendicular to the bottom surface of the slope and the bottom surface respectively. The manufacturing method comprises configuration of rock-like materials, joint manufacturing, model setting and maintenance. Based on regulation of the proportions of the materials, the materials with different strength characteristics can be formed; a side face setting apparatus of the model is composed of strip-shaped moulds connected by bolts, the upper bottom surface and the lower bottom surface are made of plates, and the size of the side slope model and the side slope tilt angle are controlled by the moulds; and the joints in the model are formed by inserting soft and weak sheets in an etching groove. The model manufactured by the manufacturing method is simple in structure and low in manufacturing cost, and can be used for researching the influence of the joints in different forms and different positions on side slope failure mechanism.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and relates to a model of a joint rock slope and a preparation method thereof. technical background [0002] my country is a country with frequent occurrence of geological disasters, with various types and wide distribution range, among which the disaster caused by slope collapse is the most serious. In rock mass engineering such as water conservancy, transportation and open-pit mining, there are a large number of rock slopes, especially in open-pit mining, with the increase of mining depth, many extra large high and steep rock slopes are gradually formed. The rock mass is composed of structural planes and structural bodies. The existence of structural planes makes the structure of the rock mass complex and the strength is greatly reduced; in rock slopes, the existence of joints often has a decisive effect on the stability of the slope. The instability and failure of rock slopes usu...
