摘要通过膨胀试验研究不同水化学环境下泥质岩的胀缩性能，分析层理面方位、同种类不同浓度、同浓度不同价位阳离子以及不同化学路径对泥质岩胀缩性的影响规律。并结合扫描电镜能谱分析，探讨泥质岩胀缩性能发生变化的内在机制。结果表明：(1) 泥质岩膨胀性随岩样端面与层理面夹角的增大而减小。(2) 泥质岩膨胀性受溶液浓度和阳离子价的共同影响。同种类水溶液中，溶液浓度越高，膨胀性越差；同浓度同种类阴离子水溶液中，阳离子价位越高，膨胀性越差；不同种类浓度水溶液中，膨胀性与其所经历的化学路径有关。(3) 当膨胀性低的水溶液置换膨胀性高的水溶液后，泥质岩将发生体积收缩。(4) 泥质岩膨胀性与其所含交换阳离子中低价阳离子与高价阳离子的比值有关，比值越大，膨胀性越强。

Abstract：The swell-shrink properties of argillaceous rock under varying aqueous environmental chemistry were studied by free swell test. Influence of the orientation of bedding，the same kind and different concentration aqueous solution，the same concentration and different valences of cation aqueous solution，the different chemical paths on the free swelling of argillaceous rock were analyzed. The essential mechanism of swelling and shrinkage variant of argillaceous rock were discussed by using SEM-EDS. Following results have been gotten：(1) The swelling of argillaceous rock decreases with the increases of angle between the horizontal plane of the device and the bedding plane of rock sample. (2) The concentration and cation valences of aqueous solution strongly influence the swelling and shrinkage of argillaceous rock under saturated conditions. The more concentrated the solution is，the weaker the swelling is under same kind aqueous solution. The more valence the cation is，the weaker the swelling is under same concentration and same negative ions kinds aqueous solution. The swelling and shrinkage of argillaceous rock connected with its go through chemical path under different kinds and different concentrations. (3) Argillaceous rock shrank when the low-concentration and low-valence cations aqueous solutions were displaced by the high-valence cations. (4) The swelling of argillaceous rock is connected with the proportions of low-valence and high-valence cations in the sample；the bigger the proportion is，the stronger the swelling is.

Key words： rock mechanics argillaceous rock aqueous environmental chemistry swell-shrink property cation
