Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering geotechnical testing, and relates to a portable multifunctional soil mechanical property testing device. Background technique [0002] Foundation pit engineering and underground engineering often need to measure soil physical and mechanical parameters in the investigation stage. At present, most of the methods used are to take samples and send them to the laboratory for testing. However, in the process of transportation and storage, soil samples are often disturbed twice, which affects the accuracy of soil mechanical parameters, which will cause risks to later engineering design and construction. In addition, due to the long laboratory test cycle, the test data is often not obtained in time, which will increase the project cycle. [0003] The Chinese invention patent with the application number 201210390847.6 discloses a test device for real-time measur...
