摘要：
A method of reducing the swell potential of an expansive clay mineral. The method includes (a) carrying out a forcefield-modified molecular level simulation to determine an amount of a swelling reduction agent to be incorporated into the expansive clay mineral to form a swelling reduction agent incorporated expansive clay mineral with a reduced swell potential Si(ECM) that is no greater than a pre-set level T, wherein the swelling reduction agent comprises at least one cementation material of calcite, gypsum, and potassium chloride and/or at least one exchangeable cation of K+, Ca2+, and Mg2+, and wherein the forcefield-modified molecular level simulation comprises molecular mechanics, molecular dynamics, and Monte Carlo simulation techniques configured to simulate the reduced swell potential Si(ECM), and (b) incorporating the amount of the swelling reduction agent into the expansive clay mineral to form the swelling reduction agent incorporated expansive clay mineral.
