A comprehensive simulation test body for practical training and teaching of geotechnical testing technology

Abstract

The present invention discloses a comprehensive simulation test body for the practical training of the rock-soil test technology. The test body comprises a standard defect cross-borehole acoustic wave detection unit, an adjustable deep horizontal and vertical displacement test unit, a low-strain simulation test unit, and an ultrasonic rebound, seam deep, reinforced steel bar distribution and anchor cable stress simulation test unit. The standard defect cross-borehole acoustic wave detection unit is used for detecting the pile body construction quality of large-diameter cast-in-situ bored piles. The adjustable deep horizontal and vertical displacement test unit is used for conducting the simulation monitoring for the soil body horizontal and vertical deformation at different depth positions inside a large-scale soil material structure. The low-strain simulation test unit is used for detecting the engineering quality of simulated worksite based piles or simulated anchor rods. The ultrasonic rebound, seam deep, reinforced steel bar distribution and anchor cable stress simulation test unit is used for measuring the strength based on the simulated ultrasonic rebound synthesis method, measuring the depth based on a shallow fracture, measuring the reinforced steel bar distribution, installing and testing a rock bolt extensometer. According to the technical scheme of the invention, the practical training content is designed corresponding to the teaching plan arrangement and the theoretical knowledge, so that the teaching quality is improved.

Description

technical field [0001] The invention belongs to the field of testing and training teaching for rock and soil professionals, and in particular relates to a comprehensive simulation test body for rock and soil testing technology training and teaching. Background technique [0002] Through geotechnical testing technology, information and data on project geological data, foundation mechanical parameters and foundation engineering quality can be obtained. Therefore, geotechnical testing technology is widely used in multiple stages of engineering construction, such as survey, design, and construction. It is an extremely important practical teaching link in the professional teaching system such as geotechnical engineering. To make students familiar with the principles of various testing methods, master the installation and operation of various testing equipment, and independently think and solve practical problems encountered in the testing process is the training goal of the train...

Problems solved by technology

[0003] At present, colleges and universities that offer this course either take out equipment in the laboratory to demonstrate experiments to students according to the teaching schedule, or contact the construction unit to practice teaching on site, but this is random and unstable, and due to safety and non-professional qualifications, etc. factors, it is impossible for students to actually operate the equipment

In addition, some colleges and universities such as Feng Shaojie use advanced virtual experiment teaching methods to allow students to conduct experiments in the environment simulated by computer software. Although this method allows students to understand the principle of the experiment to a large extent, it can repeat the deduction and testing process in the virtual construction site. But still not as intuitive and profound as real experiments
