Abstract

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
