摘要

摘要: 通过理论分析和试验验证,提出了一个固化土结构的形成模型。该模型认为:粉土固化土结构是由固化剂水化物充分包裹胶结土颗粒和填充土颗粒间孔隙而构成;黏性土固化土结构是通过固化剂水化物包裹胶结土团粒、填充土团粒间孔隙、挤压填充土团粒内孔隙而构成。该模型可以较好地反映固化剂掺量和种类与固化土强度增长规律间的关系。该模型指出,对于不同土质类型,固化剂可能产生的水化物种类,对固化剂优化设计具有指导作用。

Abstract: Based on theoretical analysis and experimental research, a structure formation model of stabilized soil is verified.The model shows that: 1) structure of the stabilized soil from silt is formed by hydrates, which are generated by hardening agent hydration, wrapping and cementing soil particles and filling pores among the particles; 2) structure of the stabilized soil formed from clayey soil is formed by the hydrates wrapping and cementing clay particle groups, filling pores among the groups, and squeezing and filling pores in the groups. By the model, the relationship between dosage and varieties of hardening agent and the strength increasing law of stabilized soil can be interpreted reasonably. The model revealed that different kinds of hydrates should be generated by hardening agent for different kind of soil, which is of important guiding significance for optimization design of hardening agent
