摘　　要：提出了一个固化土结构形成模型,根据此模型讨论了形成最佳固化土结构所需要的水化物种类;探讨了土的化学性质因素对固化土中水化物生成的影响,并给出了解决办法;在此基础上,提出了根据不同土样的性质指标设计软土固化剂的方法。A stabilized-soil structure formation model is proposed. Based on the model, hydrates varieties required to form optimum structure of the stabilized soil are suggested. Also the influence of some chemical factors in soils on hydrates growing in the stabilized soil is discussed and the resolvent is given. Based on the above research, an optimization design method is proposed, with which stabilizer can be designed according to characteristics of soil samples.
