工程地质资料检索系统的设计和应用

Design and Application of Engineering Geological Data Retrieval System

铁路工程地质勘察资料数量非常庞大,单条线路的工程地质资料超过1 TB,其中大部分是文档、图像等非结构化数据,这些资料反映了岩土工程特点和地质条件,是工程设计阶段最重要的依据。在项目工期紧和质量要求高的大背景下,传统的资料查阅方式给工程设计人员造成相当大的困扰,急需设计实现一套快速、扩展性强、支持众多文件格式的资料检索系统,以提高资料检索的速度、准确度,同时贴合设计人员使用习惯,以更丰富的检索体验来提高设计工作效率。该文分析了铁路工程地质勘察资料检索的特点,解决了系统设计的架构和处理流程,涵盖了海量、非结构化数据清洗、转换、结构化、挖掘等分析过程,实现了工程地质资料检索系统,该系统能够在秒级时间内完成百万级资料检索,命中率达80%以上。

The amount of railway engineering geological survey data is quite big, average of each single line is more than 1 TB,most of which are unstructured data such as documents and pictures, which reflect the characteristics of geotechnical engineering and geological conditions and are the most important basis in the engineering design stage. Under the background of tight project schedule and high-quality requirements, the traditional way of data search has caused considerable trouble to engineering designers. Therefore, it is urgent to design and implement a document retrieval system with abilities of fast searching, strong expansibility and supporting many file formats, so as to improve the speed and accuracy of data retrieval, and to improve the efficiency of design with richer retrieval experience while conforming to the usage habits of engineers. We analyze the characteristics of railway engineering geological survey data, solve the system design architecture and processing, cover the vast and unstructured data cleaning, conversion, and structured process analysis, mining, and realize engineering geological information retrieval system. The system can complete million level data retrieval in seconds, with a hit rate of more than 80%.
