Abstract

Abstract

The microbiology is introduced in foundation treatment.Several carbonate-mineralization microbes and polysaccharides viscose microbes are screened and isolated, and microbes ATCC6453 , No.3 and No.5 are used in silt modification.Engineering properties of silt before and after modification are compared by unconfined compressive strength test and indoor seepage test.The microstructures of silt incorporating different microbes are analysed by mean of scanning electron microscope, the modification mechanism of silt is revealed. These studies indicate that certain engineering properties of silt can be improved by incorporating microbes.
- silt,
- microbe,
- permeability coefficient,
- unconfined compressive strength,
- microstructure,
- modification mechanism
