摘　　要：探讨了拟加固土的化学性质因素对固化剂水化物生成的影响和对策、形成最佳固化土结构需要的水化物体系特点、不同种类水化物生成过程的协调性及调控方法.在此基础上,根据工业废渣在制备软土固化剂中的技术优势,提出了利用工业废渣制备软土地基固化剂的设计思想与方法,并给出设计实例.试验结果表明利用工业废渣制备固化剂时采用本设计方法,固化土28 d无侧限抗压强度比水泥固化土提高了1.5~2.75倍.Such problems were discussed as the influence of chemical factors in soil on hydrates growing in stabilized soil and the countermeasure to eliminate the influence, the system character of hydrates to form optimal stabilized soil structure, the concordance of growing process between cementitious hydrates and expan- sible hydrates and control method to the concordance. On this basis, according to the technical advantages of industrial wastes in prepare stabilizer the design thought and method for the soft soil stabilizer prepared with industrial wastes was proposed and an example was presented. Experimental results show that according to this design method, the 28d unconfined compressive strength of stabilized soil stabilized by the stabilizer prepared with industrial wastes is 1.5 - 2.75 times higher than that of stabilized soil by cement.
