Technical Field

[0001] The utility model relates to the technical field of rock and soil monitoring, in particular to a tensile testing device for rock and soil monitoring. Background Art

[0002] Tensile strength is an important indicator to measure the mechanical properties of rock mass. It is of great significance in engineering practices such as road construction, water conservancy construction, disaster prevention and slope protection. Previous studies have mostly ignored the role of tensile strength in geotechnical engineering. With the substantial advancement of domestic infrastructure, tensile failure problems such as rock mass collapse and pavement structure damage have become increasingly prominent, attracting much attention. However, the existing tensile test device for geotechnical monitoring is not highly adjustable, resulting in poor test applicability. Therefore, we introduce a tensile test device for geotechnical monitoring. Utility Model Content
