Geotechnical synthetic material straight shearing and drawing integrated testing device capable of exerting dynamic loads

Abstract

The invention provides a geotechnical synthetic material straight shearing and drawing integrated testing device capable of exerting dynamic loads; the testing device comprises a base with a horizontal moving platform and a testing box body arranged on the horizontal moving platform; a geotechnical synthetic material sample is arranged in the testing box body; the testing device further comprisesa horizontal loading mechanism and a normal loading mechanism, and a control system, wherein the horizontal loading mechanism and the normal loading mechanism can output static loads or dynamic loads;and the control system is provided with a computer processing unit and a data monitoring terminal. According to the geotechnical synthetic material straight shearing and drawing integrated testing device capable of exerting dynamic loads, the static load or dynamic load is applied to the geotechnical synthetic material sample, and then selection can be carried out according to requirements in thetest process; and when the dynamic load is applied, the working conditions of the geotechnical synthetic material sample in the actual engineering using process can be simulated in the test process,so that the measured test data can reflect the data of the geotechnical synthetic material in the actual project more truly, and the test effect is improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical testing equipment, in particular to a geosynthetic direct shearing and pulling integrated testing device capable of applying dynamic loads. Background technique [0002] Geosynthetics have the advantages of high strength, great flexibility, strong durability, low cost, convenient construction, and can form a composite structure with the soil to increase the strength of the soil. They have been widely used in engineering, involving engineering fields including geotechnical engineering, Water conservancy engineering, environmental engineering, traffic engineering, municipal engineering, land reclamation engineering, etc. In engineering, geosynthetics are placed inside or on the surface of the soil or combined with other materials and structures to achieve functions and functions such as reverse filtration, drainage, anti-seepage, reinforcement and protection, thereby effectively solving the rel...

AI Technical Summary

Problems solved by technology

[0004] Although most of the experimental devices in the prior art can perform pull-out or direct shear tests, they are generally tested through two separate loading systems, that is, the loading systems used are all set separately, so the overall structure is relatively complex and bulky , the equipment utilization rate is low and the space occupied is large. At the same time, when the current test equipment for direct shearing and pulling of geosynthetics is tested, almost all of them are carried out under the action of static load, which is different from the role of geosynthetics in actual engineering. The effect is quite different, that is, the existing static load test results cannot accurately reflect the data of geosynthetics in actual engineering
