摘要尽管在岩体加固和封堵工程中微生物注浆已有初步应用，但关于倾斜岩石节理微生物注浆扩散机制和封堵效果影响因素的研究鲜见报道。为此，通过3D打印技术制备具有不同节理倾角的缓倾角粗糙岩石节理试件，对其开展基于微生物诱导碳酸钙沉积（MICP）的微生物注浆室内试验，获得微生物注浆过程中缓倾角岩石节理试件中碳酸钙扩散沉积情况和对应的导水系数演化规律。结果表明：节理倾角是影响缓倾角岩石节理微生物注浆过程中碳酸钙扩散沉积的关键因素之一，试件中微生物注浆浆液扩散区域主要在第1轮注浆完成，对应浆液扩散面积随注浆时间呈三阶段变化趋势，即初始线性扩散期、非线性加速扩散期和碳酸钙填充密实稳定期，该变化趋势可采用指数衰减函数经验模型进行定量描述，拟合结果相关系数达0.9；具有不同节理倾角的缓倾角岩石节理试件分别经历2～5轮微生物注浆后被完全封堵，其导水系数平均降幅在99%以上，微生物注浆封堵效果显著，但受节理倾角等因素影响，个别岩石节理试件中微生物注浆体分布不均匀，可能影响微生物注浆封堵长期效果。上述研究成果可为微生物注浆技术在裂隙岩体加固和封堵工程实践提供技术支撑和参考。

Abstract：Although biogrouting has been preliminarily applied to rock-mass reinforcement and sealing, little research has investigated its diffusion mechanism and sealing performance in inclined rock joints. To address this gap, rough rock-joint specimens with different inclination angles were fabricated using 3D-printing technology, and laboratory MICP-based biogrouting experiments were conducted. The diffusion of calcium carbonate and the corresponding variations in transmissivity were monitored in gently inclined rock joints during the biogrouting process. The results indicate that the joint inclination angle is a key factor governing calcium carbonate diffusion. Most of the grouting-induced diffusion occurred during the first grouting cycle, and the evolution of the diffusion area exhibited three distinct stages with increasing grouting time: an initial linear-diffusion stage, a nonlinear accelerated-diffusion stage, and a dense stabilization stage associated with calcium carbonate filling. This evolution was quantitatively described by an empirical exponential-decay function, with a correlation coefficient of approximately 0.9. Moreover, the gently inclined rock-joint specimens with different inclination angles were completely sealed after 2–5 grouting cycles, and their transmissivity decreased by more than 99% on average, demonstrating the significant effectiveness of biogrouting in sealing inclined rock joints. However, owing to the influence of joint inclination, the distribution of the biogrouting products within some specimens was nonuniform, which may compromise the long-term sealing performance. These findings provide technical support for the practical application of microbial grouting in the reinforcement and sealing of jointed rock masses.
