| Zusammenfassung: | The invention relates to a deep-sea loose sediment high-confining-pressure low-effective-stress loading control device and method. An air inlet of an electric proportional pressure reducing valve in the device is connected with an air source, an air outlet of the electric proportional pressure reducing valve is connected with a confining pressure micro-variable cross-section pressure regulator assembly and a back pressure micro-variable cross-section pressure regulator assembly which are connected in parallel, an outlet of the confining pressure micro-variable cross-section pressure regulator assembly is connected with a triaxial pressure chamber, and an outlet of the back pressure micro-variable cross-section pressure regulator assembly is connected with deep sea loose sediments. And the confining pressure and back pressure high-precision differential pressure meter is connected with the triaxial pressure chamber and the deep sea loose sediments. Compared with the prior art, both the confining pressure micro |
