عنوان مقاله [English]
Population increase in the world has caused the cities to develop. There is a definite link between this development and availability of soil quality and stability. One of the latest methods for stabilization of soils is the use of calcium carbonate microbiological sediment as a suitable injection material. This method, not only is a compatible method with the environment, but also is a suitable method for stabilization of sandy soils. Although, there are a few studies on this topic, most of them are about construction conditions and parameter variations. Also, there is no research on soil behavior models after stabilizing sandy soils. Therefore, in this study, the effects of using a bacterium spore called Bacillus Pasteurii and production of biological deposition of calcium carbonate on improvement of the technical characteristics of sandy soils through the production of sandstone have been investigated and the effects of biological cementation on sandy soil behavior models are assessed.
