In this paper, properties of compression resistance, freeze-thaw resistance and seepage resistance of fly ash stabilized soil with 11% stabilizer HAS and 15% stabilizer HAS are studied.

Total tail is solidified by different HAS solidified agent of different gypsum content.

Test research for the properties of soil stabilizer and film to prevent seepage;

Prospect of researches on soil stabilizer;

Comparison of different construction techniques for the catchment area with soil stabilizer;

Impact on soil solidifying agent to different soil characteristics;

With the loess solidifying testes used with soil solidifying agent and cement, the physics and mechanics characteristics of different solidifying loess are analyzed and compared, and it is considered that the soil solidifying agent can be used to the seepage prevention and freezing resist and the base treatment of trench in loess area.

The present application condition, classification of soil solidifying agents and strengthening mechanism were given, the problems existed in present application of solidifying agent were summarized, and it was put forward that undisturbed strengthening technology based on soil mini-structure should be developed.

Study on engineering properties of improved soil by GT soil firming agent;
