Abstract
The present disclosure provides a supergravity simulation system for in-situ stress field and seepage field for deep earth engineering, comprising: a triaxial pressure chamber for placing a model and providing in-situ axial pressure, confining pressure and seepage field of deep earth structure; a simulation control device for providing pressure liquid and pore water to the triaxial pressure chamber to generate the aforementioned axial pressure, confining pressure and seepage field, and controlling the values of the axial pressure, confining pressure and seepage field; a signal acquisition device for monitoring the deformation and seepage process of the model during the test. The invention improves the similarity, reliability, and accuracy of the simulation test, and it can output pressure with an accuracy of 1% or constitute the pore water pressure difference with an accuracy of 1% to the triaxial pressure chamber through the command of the control unit.
