Engineering structures such as buildings, highways, bridges, tunnels, dams and offshore oil platforms are all built on or in soils and rocks. The ability to predict the response of these materials under various loading conditions is therefore of major importance in civil engineering design. The traditional method in modelling these materials requires extensive and often costly experimental data. The proposed micro-macro modelling approach will enable us to take advantage of the fast-growing computing power to release some of the pressure in geotechnical testing. It will also improve the quality of engineering analysis and hence leads to more efficient and effective engineering design.

建筑物、高速公路、桥梁、隧道、水坝和海上石油平台等工程结构都建在土壤和岩石上或土壤和岩石中。因此，预测这些材料在各种载荷条件下的响应的能力在土木工程设计中具有重要意义。对这些材料进行建模的传统方法需要大量且通常昂贵的实验数据。建议的微观-宏观建模方法将使我们能够利用快速增长的计算能力来释放岩土测试中的一些压力。它还将提高工程分析的质量，从而提高工程设计的效率和效益。
