微生物矿化反应原理、沉积与破坏机制及理论:研究进展与挑战
Reaction principles,deposition and failure mechanisms and theories of biomineralization:progress and challenges
摘要
Abstract
The biomineralization is an integral part of geological evolution and carbon-nitrogen cycle,and it has brought new opportunities and challenges in the geotechnical,water conservancy and environmental fields.The inspired bio-geotechnical technology represented by the MICP process has become one of the most innovative technological topics in the environmental geotechnical engineering.In the last two decades,the bio-geotechnical technology has made significant progress from the proof-of-concept phase to the technology demonstration in the relevant environments.In order to promote more comprehensive and in-depth basic understanding and researches on this topic,a systematic review of the MICP technology is performed,focusing on the following three parts:biochemical principles of urease-producing bacteria-induced biomineralization,precipitation patterns and failure mechanisms of bio-cemented soil,and theories of biomineralization reaction under the multi-physics coupling effects of bio-chemo-hydro-mechanical model.Furthermore,the current problems and challenges of bio-geotechnical technology are summarized,and the potential research hot spots and application prospects are discussed.关键词
