背景技术Background technique
微生物固土作为岩土和地质工程领域新兴的一种固化土体技术，近些年受到广泛关注。Microbial soil stabilization, as an emerging soil stabilization technology in the field of geotechnical and geological engineering, has received widespread attention in recent years.
现阶段比较成熟的微生物固化技术主要为微生物诱导碳酸盐沉积技术(Microbial induced calcite precipitation，以下简称MICP)，该技术通过微生物催化水解尿素得到的碳酸根离子与土体中的钙离子结合生成的碳酸钙沉淀，将土颗粒包裹、黏结或填充孔隙，从而达到固化土体的目的；因其具备的优势特点，目前已应用于改善土体抗渗性和抗液化能力、土体抗风蚀处理、海岸侵蚀防护、地基加固、提高边坡稳定性等方面，具有强大的发展潜力和应用前景。The relatively mature microbial solidification technology at this stage is mainly Microbial induced calcite precipitation (hereinafter referred to as MICP). This technology is generated by combining carbonate ions obtained by microbial catalytic hydrolysis of urea with calcium ions in the soil. Calcium carbonate precipitates, wrapping, bonding, or filling pores of soil particles to achieve the purpose of solidifying the soil. Because of its advantages and characteristics, it has been used to improve soil impermeability and liquefaction resistance, soil resistance to wind erosion, It has strong development potential and application prospects in coastal erosion protection, foundation reinforcement, and improving slope stability.
目前与MICP技术相关的试验装置和固化效果测定方法大多是服务于测定固化后的土体的宏微观参数，如抗压强度、渗透性、微观形貌等，将固化后和未固化试样的宏微观参数进行对比分析，以此评价MICP技术固化效果；但是这些试验装置和固化效果评价方法无法探究整个微生物固化过程中土层的变化规律，难以系统定量评价微生物固化坡体表层效果。At present, most of the test devices and curing effect measurement methods related to MICP technology serve to measure the macro and micro parameters of cured soil, such as compressive strength, permeability, micro morphology, etc., and compare the cured and uncured samples. Comparative analysis of macro and micro parameters is conducted to evaluate the curing effect of MICP technology; however, these test devices and curing effect evaluation methods cannot explore the changing rules of the soil layer during the entire microbial curing process, and it is difficult to systematically and quantitatively evaluate the effect of microbial curing on the slope surface.
