| 中文摘要: |
| 脲酶诱导碳酸钙沉淀(EICP)是一种以植物源脲酶催化尿素水解并诱导碳酸钙沉淀形成的绿色生物矿化技术。本文综述了EICP在土体加固、生物砖制备、风蚀防治、砂土抗液化及土体导热改良等方面的研究进展,归纳了酶源、pH、温度、反应物浓度及施工工艺对加固效果的影响机制。结果表明,EICP具有环境友好、渗透性好和适应性强等优势,但仍面临加固均匀性不足、复杂环境下耐久性机理不清及成本偏高等问题。 |
| 英文摘要: |
| Enzyme-induced carbonate precipitation (EICP) is a green biomineralization technique in which plant-derived urease catalyzes urea hydrolysis and induces calcium carbonate precipitation. This paper reviews recent advances in the application of EICP to soil improvement, bio-brick production, wind erosion control, liquefaction mitigation, and thermal conductivity enhancement. The influencing mechanisms of enzyme source, pH, temperature, reactant concentration, and construction method on treatment performance are summarized. Existing studies indicate that EICP has notable advantages in environmental compatibility, permeability, and adaptability. However, challenges remain in treatment uniformity, durability under complex service conditions, and cost control. |
