In-situ frequency-controllable electrical pore pressure static sounding testing device
The invention discloses an in-situ frequency-controllable electrical pore pressure static sounding testing device which comprises an electrical testing probe rod at the upper part and a pore pressure static sounding annular probe at the lower part. In the electrical method test probe rod, a coaxial radio frequency probe is connected to the bottom of a coaxial transmission cable, the top of the coaxial radio frequency probe is connected to a test analyzer through a frequency regulator, and four annular detection electrodes are uniformly sleeved on the coaxial transmission cable at intervals. When the high-frequency dielectric constant is tested, the coaxial transmission cable transmits electromagnetic waves to a peripheral soil layer, the coaxial radio frequency probe receives electromagnetic wave signals reflected by the soil layer, and the test analyzer calculates the dielectric constant according to the intensity of incident and reflected electromagnetic wave signals. During low-frequency resistivity testing, the two electrodes at the upper end and the lower end serve as emission electrodes and are used for emitting current to a soil body, the two electrodes in the middle serve as testing electrodes and are used for measuring the potential difference, and the testing analyzer calculates the soil resistivity according to the voltage drop between the two testing electrodes under the constant emission current.
