Abstract:

The engineering properties of Marine soft soil of Tianjin Binhai New Area is difficult to directly meet the requirements of constuction, so need for appropriate treatment and disposal. The effect of solidification of soil-cement adding alkaline agent based on raw materials of tianjin marine soft soil and analysis of filed verification test and microstructure are introduced. The results indicate that alkaline environment has a great role in improving the strength of cement-soil; and also can save the cost of project construction, it is worth to appliying in project practice.

Key words: marine soft soil, alkaline environment, the effect of solidification, microstructure
