	微生物诱导碳酸钙沉积(MICP)是一种新型的绿色加固技术，在岩土工程领域中具有强大的应用潜力。然而，关于微生物诱导碳酸钙沉积的加固工艺方面研究较少。为了确定MICP加固试验中的最佳加固工艺，通过不同加固工艺的MICP加固试验，研究了不同加固工艺下MICP加固砂土效果。研究结果表明：采用双相加固工艺能够使得MICP反应更充分，碳酸钙沉淀更均匀的填充于砂样孔隙间，显著提高砂样的结构强度，具有较好的适应性。该研究结果对于提升MICP加固效果和均匀性方面有较大的参考意义。<br />
Microbial Induced Carbonate Precipitation is a new green reinforcement technology, it has great application potential in the field of geotechnical engineering. However, there are few studies on the reinforcement technology of Microbial Induced Carbonate Precipitation. In order to determine the best reinforcement technology in MICP reinforcement test, through the MICP strengthening tests of different strengthening technologies, the effects of different strengthening technologies on sand reinforcement are studied. The results show that the two-phase reinforcement process can make MICP reaction more sufficient, calcium carbonate precipitation more evenly filled in the pores of sand samples, significantly improve the structural strength of sand samples, and has good adaptability. The research results have great reference significance for improving the reinforcement effect and uniformity of MICP.
