Abstract:

With the widespread application of digital twin technology in deep foundation pit support engineering,the cross-integration of terms in the two fields has brought about confusion in terms and inconsistent definitions,which has affected academic exchanges and technology promotion.Through literature research,standard analysis and field visits,this paper systematically collected relevant terms in the digital twin system of deep foundation pit support engineering,and established a preliminary terminology library containing 487 terms.The study analyzed the current status of terminology use and the main confusion points.In response to these problems,principles for terminology standardization were proposed.The core terms such as “digital twin system of deep foundation pit support engineering”were standardized and defined,and a three-level classification system of “main domain-subdomain-terminology group”was constructed.

Key words: Deep foundation pit support engineering, Digital twin, Terminology standardization, Terminology system
