| 摘要： | Soil is a living ecosystem where biogeochemical processes such as mineral precipitation, gas generation, biofilm formation and biopolymer generation are ubiquitous. Microbially induced calcite precipitation (MICP) is a sustainable method and a bio-geochemical process that induces calcium carbonate precipitation within the soil matrix as a consequence of microbial metabolic activity. MICP is one type of microbial geotechnical approaches for soil stabilization. It has recently gained much attention from geotechnical engineering researchers worldwide. The objective of this study is to induce biocementation through MICP to provide an alternative approach for soil improvement and for in-situ improved geomaterials to resist bridge scour and road shoulder erosion. |
