The invention provides a gas-containing soil consolidation test device and a test method. The gas-containing soil consolidation test device comprises a support, a pressure
barrel, a
piston, a
top cap,a perforated plate, a guiding rod, a displacement sensor, a total
stress sensor, a steam
measurement device, a
measurement device for
pore water pressure of the upper surface and the lower surface ofa soil sample to be tested, a water inlet and a guiding
pipe, wherein the pressure
barrel is fixed to the support, the
piston is arranged in the pressure
barrel, the guiding rod is arranged at the bottom of the
piston, the displacement sensor is arranged at the bottom of the support and connected with the guiding rod, the
top cap and the perforated plate are arranged on a consolidation chamber from top to bottom, the total
stress sensor is arranged on the upper surface of the piston, the steam
measurement device is arranged on the
top cap, the water inlet is arranged on the pressure barrel, the guiding
pipe is arranged on the piston, the water inlet is communicated with a pressure chamber and is externally connected with external pressurizing equipment, and the measurement device for porewater pressure of the upper surface and the lower surface of a soil sample to be tested is respectively communicated with the upper surface and the lower surface of the soil sample to be tested. Thegas-containing soil consolidation test device disclosed by the invention can be suitable for gas-containing soil, can perform
moisture separation in a gas sealing and
consolidation process and achieves independent measurement.
