This study investigates the key problems in the construction of a borehole core basic database (borehole core test, data processing, and data collection) and proposes a design scheme for the borehole core basic database. Taking the borehole construction at Changshu station in Jiangsu Province as an example, based on the newly issued construction standard (Specification for the Construction of Seismic Station Crust Deformation Station-Part 2: Crust Tilt and Strain Observatory in Borehole), some key works include borehole construction process, core experiment steps, and the development of core data processing and analysis software. The design scheme of the basic database provides detailed research ideas, methods, and examples for the collection and testing of borehole cores. This study fills the gap in terms of identifying new technical indicators in the national borehole standardization construction and provides a reference for the construction of the borehole core basic database in China.
