微生物诱导碳酸盐沉降法是一种很有前途的地基处理技术。为了使MICP从实验室规模的过程发展为商业上可行的替代地基改良方案，需要将现场试验和现场规模的过程模拟结合起来。我们给出了一个现场规模的模型的结果，其中评估了不同的注入策略，发现更长的处理时间可以更有效地利用试剂，但可能会带来更高的操作成本，并且使用多个具有不同反应动力学和传输特性的细菌菌株可能会提高效率。
Microbially induced carbonate precipitation is a promising technique for ground improvement. In order for MICP to progress from a lab-scale process to a commercially viable alternative ground improvement option, a combination of field-trials and field-scale modelling of the process is required. We present the results of a field-scale model in which differing injection strategies are evaluated and find that longer treatment times make more efficient use of reagents, but may come with higher operational costs, and that utilising multiple strains of bacteria with different reaction kinetics and transport properties may improve efficiency.
