Device and method for intelligently controlling seepage consolidation deformation of soil core wall of high earth-rock dam

The invention discloses a device and method for intelligently controlling seepage consolidation deformation of a soil core wall of a high earth-rock dam. A pore water pressure sensor and a pipeline for water injection and drainage are embedded in the core wall, and various elevations exist at the lower end of the pipeline and the pore water pressure sensor. The pipeline is a thin pipe, and comprises an inverted filtering layer and a pipe body in the inverted filtering layer. The upper end of the pipe body extends out of the dam top and is connected with a pressure/volume controller through a control valve. The pressure/volume controller, the control valve, the pore water pressure sensor and a plurality of dam shell and core wall displacement monitoring devices which are arranged in a dam body at the same elevation are all connected with a control platform. The water pressure of the pressure/volume controller is adjusted through the control platform, water is injected or sucked out at different positions in th
