摘　　要：根据软土固化所需水化物组成的特殊性以及固化土结构形成过程的特点,有针对性地选择煤矸石、电石渣和磷石膏制备成以工业废渣为主要成分的软土固化剂。试验表明:采用合理的组成设计,充分利用不同工业废渣在提供碱性物质和膨胀性物质、调整胶结性水化物与膨胀性水化物生成速率协调性等方面的技术优势,利用工业废渣制备的固化剂与普通水泥相比可使固化土强度提高数倍。According to the particularity of the hydrates system needed to stabilize soft soil and the characteristic of structure formation process of the stabilized soil, soil stabilizers were prepared mainly with industrial wastes such as calcined coal gangue, carbide slag and phosphogypsum. The results indicate that based on rational component design in which the technical advantages of different industrial wastes, such as supplying alkaline hydrates and expansible hydrates, adjusting the concordance of growing process between cementitious hydrates and expansible hydrates, were fully utilized, the stabilizers prepared with industrial wastes can enhance the strength of stabilized soil by several times than cement.
