The invention discloses an environmental static sounding probe for contaminated foundation soil, which is characterized in that the periphery of the upper half section of the probe is coated with four annular electrodes, wherein the upper and lower annular electrodes are two reference electrodes (1), the middle annular electrodes are two test electrodes (2), and the annular electrodes are insulated by a plastic insulating layer (3); the lower half section of the probe is provide with a three-component seismic detector (4), a two-dimensional clinometer (5), an electrothermic regulator (6), a friction drum (7), a hole-pressure filtration ring (9) and a conical probe (10) from top to bottom; the middle of the friction drum (7) is provided with a pore water pressure sensor (8), a tip resistance pressure sensor (11) and a sidewall frictional resistance pressure sensor (12) are respectively arranged on the internal side faces of the friction drum (7), and the hole-pressure filtration ring (9) is positioned on the joint of the friction drum (7) and the conical probe (10). The probe of the invention has the advantages of in-situ, speediness, accuracy and economy, and the like, and a strong recognition tool is provided for evaluating the contaminated foundation soil in the process of environmental geotechnical engineering.
