本研究研究了耦合有限元模型模拟微生物诱导碳酸钙沉淀 (MICP) 以及水泥样品中相关愈合行为的能力。这种最新的耦合 3D 模型最初是为了模拟水泥结构元件中自主愈合系统的行为而开发的。它采用内聚区本构模型来模拟 3D 连续体元素内嵌入界面的损伤修复行为。使用质量平衡方程和达西定律模拟流体流动。愈合是通过广义固化前沿模型来计算的，该模型模拟裂缝内愈合材料的积累。本文报道的研究表明，可以校准固化前沿模型，以高精度预测水泥样本中 MICP 的愈合情况。
This study investigates the ability of a coupled finite element model to simulate Microbially Induced Calcium Carbonate Precipitation (MICP) and associated healing behaviour in cementitious samples. This recent coupled 3D model was first developed for simulating the behaviour of autonomic healing systems in cementitious structural elements. It employs a cohesive zone constitutive model for simulating the damage-healing behaviour of an embedded interface within 3D continuum elements. Fluid flow is simulated using a mass balance equation and Darcy’s law. Healing is computed via a generalised curing front model that simulates the accumulation of healed material within a crack. The research reported in this article demonstrates that the curing front model can be calibrated to predict healing from MICP in cementitious specimens with good accuracy.
