Description
technical field [0001] The invention relates to the technical field of civil engineering triaxial test equipment, in particular to a triaxial test top cap for measuring matrix suction. Background technique [0002] Air-bearing soil generally refers to the shallow gas-bearing sediments at the bottom of oceans and lakes. It is not only a kind of energy resource, but also a type of disaster geology in engineering. Air-bearing soil is generally in a critical equilibrium state under the influence of various complex factors such as soil particles, pore water, gas, pressure, temperature, and overlying layer, and is easily destroyed by outgassing due to external disturbances. , generally through simulation experiments to study the engineering properties of air-bearing soils, where the unsaturated soil matrix Suction, that is, the difference between pore air pressure and pore water pressure, is one of the important reasons for the change of its stress state. Existing measurement met...
