Abstract

Large language models (LLMs) have achieved remarkable success in various industrial and research fields, enhancing work efficiency by assisting machines in comprehending human language. In geotechnical design where extensive repetitive cross-checking of design codes consumes considerable time and labour, the utilization of LLMs to enhance design procedures has not been explored before. The challenge is to ensure that LLMs accurately comprehend professional geotechnical information from text and execute mathematical calculations correctly. This study makes the first attempt at developing a specialized LLM framework, GeoLLM, integrated with an innovative prompt engineering strategy to extract professional information from text and enable accurate mathematical calculations. GeoLLM is applied to the design of single piles involving bearing capacity and settlement calculations. The results reveal that GeoLLM exhibits excellent performance in single pile cases. Additionally, compared with LLMs of varying architectures and sizes, commercial LLMs with over 100 billion parameters presented outstanding comprehensive capacities, while those with 1.8 ∼ 72 billion parameters degraded relatively. These findings indicate the promising capacity of GeoLLM to address professional tasks in geotechnical design.
GeoLLM:用于智能岩土工程设计的专用大型语言模型框架
大语言模型(LLMs)通过辅助机器理解人类语言,提高了工作效率,在各个工业和研究领域都取得了显著的成就。在岩土工程设计中,设计规范的大量重复性交叉检查耗费了大量的时间和人力,而利用 LLMs 来改进设计程序则是前所未有的。如何确保 LLM 能够准确理解文本中的专业岩土工程信息并正确执行数学计算是一项挑战。本研究首次尝试开发专门的 LLM 框架--GeoLLM,并将其与创新的提示工程策略相结合,以从文本中提取专业信息并实现准确的数学计算。GeoLLM 被应用于涉及承载力和沉降计算的单桩设计。结果表明,GeoLLM 在单桩案例中表现出卓越的性能。此外,与不同结构和规模的 LLM 相比,拥有超过 1000 亿个参数的商用 LLM 具有出色的综合能力,而拥有 180 ∼ 720 亿个参数的 LLM 则相对较差。这些发现表明,GeoLLM 在解决岩土工程设计中的专业任务方面具有广阔的前景。

期刊介绍: The use of computers is firmly established in geotechnical engineering and continues to grow rapidly in both engineering practice and academe. The development of advanced numerical techniques and constitutive modeling, in conjunction with rapid developments in computer hardware, enables problems to be tackled that were unthinkable even a few years ago. Computers and Geotechnics provides an up-to-date reference for engineers and researchers engaged in computer aided analysis and research in geotechnical engineering. The journal is intended for an expeditious dissemination of advanced computer applications across a broad range of geotechnical topics. Contributions on advances in numerical algorithms, computer implementation of new constitutive models and probabilistic methods are especially encouraged.
