Multiphysics processes and different levels of mutual coupling have been observed in various aspects of geotechnical and environmental engineering and of energy production, such as waste disposal (including nuclear waste) and soil pollution problems where heat effects add to the complexity of multi-phase couplings, hydro-mechanical interactions during hydraulic fracture of shale or other tight rocks in oil and gas industry and slope failure induced by infiltration of water into the ground surface. It is not sufficient to solely carry out analysis on each physical process separately for these complicated engineering problems. Instead, it is crucial to consider their mutual coupling in the analysis. These processes cover different scales, from particle size to much larger engineering scales. Therefore, it is required to study the performance of relevant infrastructures by considering various coupled multiphysics processes on multi-scales.

在岩土工程、环境工程和能源生产（如废物处理）的各个方面都观察到了多物理过程和不同程度的相互耦合（包括核废料）和土壤污染问题，其中热效应增加了多相耦合的复杂性，水，氢油气工业中页岩或其他致密岩石水力压裂过程中的力学相互作用以及水渗透引起的边坡破坏进入地面。对于这些复杂的工程问题，仅仅对每一个物理过程分别进行分析是不够的。相反，在分析中考虑它们的相互耦合至关重要。这些过程涵盖不同的尺度，从颗粒大小到更大的工程尺度。因此，需要研究相关基础设施的性能，考虑各种耦合多物理过程在多尺度上。
