Geotechnical borehole information is often used for liquefaction hazard mapping, but can be highly variable in terms of quantity and quality. In addition, geotechnical borehole logs are often provided as images in reports rather than delivered in a structured, queryable database, which makes the logs and supplementary information difficult to organize particularly across a large geographic area. In contrast, surficial geologic mapping is generally available and often accessible in geographic information systems (GIS) format. This article’s objective is to describe the compilation of a geotechnical database for regional mapping purposes and to demonstrate the value of documenting geotechnical data into a consistent data format. Specifically, this article describes the development of three geotechnical borehole databases compiled in Utah, which has been coined the Geotechnical Database for Utah (GeoDU). The database is used to quantify geotechnical properties for subsequent liquefaction evaluations of surficial geologic units comprising similar depositional environment and age. The resulting GeoDU is an important resource for future efforts with many applications including community data sharing and planning for preliminary geotechnical site investigations.

犹他州 (GeoDU) 的岩土工程数据库能够量化地表地质单元的岩土工程特性以进行地质灾害评估

岩土钻孔信息通常用于液化危险绘图，但在数量和质量方面可能变化很大。此外，岩土钻孔日志通常在报告中作为图像提供，而不是在结构化的、可查询的数据库中提供，这使得日志和补充信息难以组织，尤其是跨大的地理区域。相比之下，地表地质图通常可用，并且通常以地理信息系统 (GIS) 格式访问。本文的目的是描述用于区域制图目的的岩土数据库的编译，并展示将岩土数据记录为一致数据格式的价值。本文具体介绍了犹他州编译的三个岩土钻孔数据库的发展情况，已创建犹他州岩土技术数据库 (GeoDU)。该数据库用于量化岩土特性，以便随后对包含类似沉积环境和年龄的地表地质单元进行液化评估。由此产生的 GeoDU 是未来许多应用的重要资源，包括社区数据共享和初步岩土工程现场调查的规划。
