According to the present invention, test requirements are met, test efficiency is increased, comprehensiveness is strong, and test operation is convenient.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a device for multidirectional loading of geotechnical engineering slopes. Background technique [0002] Slope refers to the air surface with a certain inclination formed by the action of natural gravity or human action on rock mass and soil. There are many classifications of slopes. According to the classification of origin, they can be divided into artificial slopes and natural slopes; According to the classification of stratum lithology, it can be divided into soil slope and rock slope; according to the classification of service life, it can be divided into permanent slope and temporary slope. With the development of geotechnical engineering, the slope problem has become a common problem in the engineering field. Among the influencing factors on the slope, it is necessary to analyze the stability of the slope under different loading conditions. The main method ...

AI Technical Summary

Problems solved by technology

[0003] The existing analysis and test devices for geotechnical engineering are relatively simple and loaded with heavy objects. The existing problem is that the model test device for single inclined loading cannot meet the needs of multi-load joint action tests, and cannot be used for slope damage under comprehensive effects. Make reasonable analysis and explanation, the efficiency, accuracy and practicability of the test are relatively low
