%X 近年来，脲酶诱导碳酸钙沉积(Enzyme Induced Calcium Carbonate Precipitation，简称EICP)技术在岩土领域得到广泛应用，作为一种加固土体的新型方法，EICP直接从植物中提取脲酶，催化尿素水解成碳酸根离子，与钙离子反应产生碳酸钙沉淀；所生成的游离脲酶可降解，不会对环境造成长期影响，且其尺寸小能透过孔隙更小的土体，生成碳酸钙过程中不易发生堵塞。本文从EICP的背景出发，研究了EICP的国外现状、固化土体力学特性及作用机理，为EICP固化土体进行了系统的总结。<br />
In recent years, Enzyme Induced Calcium Carbonate Precipitation (EICP) technology has been widely used in the field of rock and soil. As a new method for soil reinforcement, EICP directly extracts urease from plants, and catalyzes the hydrolysis of urea into carbonate ion, which reacts with calcium ion to produce calcium carbonate precipitation; The generated free urease is degradable, and does not have a long-term impact on the environment. Its small size can penetrate the soil with smaller pores, and is not prone to blockage during the formation of calcium carbonate. In this paper, based on the background of EICP, the present situation of EICP abroad, the mechanical characteristics and mechanism of solidified soil were studied, and the soil solidified by EICP was systematically summarized.
