膨胀土以粘土矿物为主要成分、对湿热环境变化敏感的高塑性粘土。膨胀土分布极广。多生成于盆地的边缘、谷地的高阶地。多属更新世。可有各种地质成因类型。主要特点是：①粒度组成中，粘粒含量大于30％。②粘土矿物以蒙脱石、伊利石等强亲水性矿物为主。③土体湿度增高时，体积膨胀，形成膨胀压力；土体干燥时，体积收缩，形成收缩裂缝。④膨胀、收缩随环境变化可往复发生，导致强度衰减。⑤属液限大于40％的高塑性粘土（见图）。⑥属固结性粘土。膨胀土的膨胀和收缩性常用膨胀压力、膨胀率、体缩和线缩率等指标表示。膨胀压力是土样在无侧向膨胀条件下湿化，控制膨胀变形为零时所需的压力。膨胀率则表示膨胀体积的百分率。体缩和线缩表示土样干燥前后，体变和线性变化的百分率。膨胀土易被误认为是工程地质性质较好的土，但实际上膨胀土易随湿热环境变化，产生体积变形而导致建筑物变形破坏。膨胀土由于干燥或其他原因常形成裂隙，裂隙面光滑，间而有次生土质充填，故而又称为裂隙土。常是控制边坡稳定的重要因素。
