摘要：

The primary objective of the present study was to elucidate the relative contributions of exchangeable cations and surface forces to the swelling pressure on montmorillonite. To achieve this objective, measurements were made of the amount of water imbibed by Na-saturated montmorillonites having different cation exchange capacities, b dimensions, and specific surface areas under applied pressures of 0, 1, 3, and 5 atm. The resulting data were used to develop an empirical equation.-from Authors
