不同复杂程度的土方机械，从简单的花园铲到液压挖掘机，在几个世纪以来已经有了相当大的发展，但对土方过程的科学理解远远落后于技术。从历史上看，许多努力都是针对机器的各个方面，而对土壤的关注相对较少。由于这个原因，这个问题主要引起了机械工程师的兴趣。本文简要概述了分析和数值建模的最新技术水平，以及一些尚未克服的重大挑战。它的结论与西北大学的研究计划，其中包括分析和数值模拟土方工程的过程和实验完成使用一个新的实验设施的描述。初步结果显示，在文件中突出的土方工程过程中的主要特点和潜在的岩土工程师的贡献。
Earthmoving machines of varying sophistication, ranging from the simple garden spade to the hydraulic excavator, have evolved considerably over the centuries, but the scientific understanding of earthmoving processes lags considerably behind the technology. Historically much effort has been directed towards aspects of the machine, whereas relatively little attention has been given to the soil. For this reason, the problem has primarily engaged the interest of mechanical engineers. This paper provides a brief overview of the state of the art in analytical and numerical modeling, as well as some of the significant challenges that have yet to be overcome. It concludes with a description of the research program at Northwestern University, which includes analytical and numerical modeling of earthmoving processes and experiments completed using a new experimental facility. The preliminary results shown in the paper highlight key features of earthmoving processes and the potential for contributions from geotechnical engineers.
