THE STUDY ON THE REMEDIATION OF OIL POLLUTED GROUND CONSIDERING WITH THE UNSATURATED WATER. OIL AND AIR CONDUCTIVITY.

通过压板实验和重力排水柱实验验证了经验方程对水-水-空气三相毛细管压力-饱和度关系的有效性。压板实验表明，水饱和度与气-水两相条件下的保水特性相同。另一方面，重力排水柱实验表明，三相条件下的总液饱和度与油厚较薄时气油两相条件下的留油特性不一致。另一方面，提出了一种新的测定不饱和水的装置。在不久的将来，将利用分散柱装置发展油和空气的导电性指标。

THE PRESSURE-PLATE AND THE GRAVITY DRAINAGE COLUMN EXPERIMENTS WERE TESTED TO CONFIRM THE EFFICIENCY OF THE EMPIRICAL EQUATIONS EXPLAINING THE WATER-NAPL-AIR THREE-PHASE CAPILLARY PRESSURE-SATURATION RELATIONSHIPS. THE PRESSURE-PLATE EXPERIMENTS SHOWED THAT WATER SATURATION IS IDENTICAL TO THE WATER RETENTION CHARACTERISTICS OF AIR-WATER TWO-PHASE CONDITION. ON THE OTHER HANDS, THE GRAVITY DRAINAGE COLUMN EXPERIMENTS SHOWED THAT TOTAL LIQUID SATURATION UNDER THREE-PHASE CONDITION WAS NOT AGREEMENT WITH THE OIL RETENTION CHARACTERISTICS OF AIR-OIL TWO-PHASE CONDITION, WHEN OIL THICKNESS WAS THIN. ON THE OTHER HANDS, ANEW DEVICE WHICH CAN DETERMINE THE UNSATURATED WATER. OIL AND AIR CONDUCTIVITY DIRECTRY WILL BE DEVELOPED IN THE NEAR FUTURE USING DISPERSION COLUMN DEVICES.
