Description
technical field [0001] The invention belongs to the technical field of engineering geology, and in particular relates to an intelligent testing device for soil water stability and a using method thereof. Background technique [0002] Due to its loose structure, low cohesion and easy liquefaction, loose soil has always affected the construction and use of various projects. Therefore, the research on the properties of loose soil has always been a hot spot in engineering geology, and the research on the water stability of loose soil is especially important. At present, some known test devices for soil water stability are mostly used for soil water stability evaluation under static conditions, but in actual engineering, the engineering geological environment in which the soil is located is very complex and constantly changing, so Testing of soil water stability under static conditions has unavoidable drawbacks. How to speed up the development of a new type of intelligent testi...
