ITR: Solutions for Exchange and Utilization of Geotechnical Information

CMS-0219463PI：Jean-Pierre BaradeInstitution：南加州大学标题：“ITR岩土信息交换和利用解决方案”岩土信息描述了上层土壤沉积物(通常深至50米)的特征，我们的大部分民用基础设施(例如，建筑、道路、桥梁、机场、港口和工厂)都位于这些土壤沉积物上。每年，在进行包括国家科学基金会(NSF)和许多其他地方、州和联邦机构的项目的过程中，都会付出巨大的努力和费用来产生大量的岩土信息。这些项目的数据和成果通常以硬拷贝报告的形式公布，没有数字数据。此外，数据收集和处理的步骤是用传统方法记录的，这使得数据的审查、修订和应用往往很困难，甚至不可能。1998年在南加州大学(南加州大学)举行的一次国家科学基金会讲习班明确地在研究人员和从业人员之间就更好地交流岩土信息达成了一致共识。信息技术(IT)为岩土信息的收集、交换和利用带来了新的机遇，为我国的土木工程建设提供了新的机遇。我们的研究借鉴了南加州大学自1998年以来开展的几个IT项目的最新经验，为解决与岩土信息收集、交换和利用相关的重大问题创造了ITR方法。这项研究整合了不同的信息技术方法，从实验室和现场的数据生成到参与土木工程基础设施系统的工程师和规划师的最终使用，对岩土信息进行了全面和完整的描述和利用。研究的具体目标是：1.根据领域专家对选定的岩土信息的知识定义通用的数据结构。由岩土领域专家定义元数据，描述生成岩土信息的过程，包括开发自动化元数据收集，以方便用户输入。开发岩土信息数据挖掘工具，创建集成数据和元数据的QA/QC算法。这项研究涉及开发信息技术方法，使参与规划、设计、建造和维护我们的民用基础设施系统的人能够使用岩土信息。研究期间开发的工具和方法将在五个研究合作者的现实工作环境中进行测试，这五个合作者是加州交通部(CalTrans)、洛杉矶水电部门(LADWP)、加州地质调查局(CGS)、法国地质和矿产研究局(BRGM)和日本神户大学。预期这项研究所发展的资讯科技概念，将有助建立一个虚拟的岩土资料储存库，日后由地方、州和联邦机构组成的联营机构营运。这项研究将在多方面惠及公众。它将向学生、研究人员和从业人员传播岩土信息。它将组织岩土信息，并为地方、州和联邦机构、大学和公司改进其档案和检索。它将为开发地震期间液化引起的横向传播等自然灾害的大规模地理信息系统提供一个信息平台。它将促进工程学方面的教育和研究，并促进研究人员和从业人员之间的数据交换和合作。

CMS-0219463PI: Jean-Pierre BardetInstitution: University of Southern CaliforniaTitle: "ITR SOLUTIONS FOR EXCHANGE AND UTILIZATION OF GEOTECHNICAL INFORMATION"Geotechnical information describes the characteristics of upper soil deposits (typically down to a 50 m depth) on which rest most of our civil infrastructure (e.g., buildings, roads, bridges, airports, harbors, and factories). Each year, a large amount of geotechnical information is generated with great efforts and expense during the conduct of projects, including those sponsored by the National Science Foundation (NSF), and many other local, state, and federal agencies. The data and results of these projects are usually published as hardcopy reports, without digital data. In addition, the steps in data collection and processing are documented with conventional methods, making it often difficult even impossible to scrutinize, revise and apply data. An NSF workshop, held at the University of Southern California (USC) in 1998, clearly established a unanimous consensus among researchers and practitioners for a better exchange of geotechnical information. Nowadays Information Technologies (IT) unleashes new powerful opportunities for collecting, exchanging, and utilizing geotechnical information, which should be explored for the sake of our civil infrastructures.Capitalizing on the benefits from recent experiences gained during several IT projects carried out at USC since 1998, our research creates ITR methods for resolving major issues associated with the collection, exchange and utilization of geotechnical information. The research integrates different IT methods to produce a comprehensive and complete description and utilization of geotechnical information starting from the data generation in the laboratory and field to its end usage by engineers and planners involved in civil infrastructure systems. The specific objectives of the research are:1. Define versatile data structures based on the knowledge of domain experts on selected geotechnical information.2. Define metadata by geotechnical domain experts describing the processes generating geotechnical information, including development of automated metadata collection for facilitating user input.3. Develop data mining tools for geotechnical information, and creating QA/QC algorithms integrating data and metadata. The research is concerned with the development of IT methods for rendering geotechnical information usable to those involved with planning, designing, building, and maintaining our civil infrastructure systems. The tools and methods developed during the research will be tested in the realistic work environments of five research collaborators, namely the California Department of Transportation (Caltrans), the Los Angeles Department of Water and Power (LADWP), the California Geological Survey (CGS), the Bureau of Research in Geology and Mines (BRGM) in France, and Kobe University in Japan. It is anticipated that the IT concepts developed in this research will contribute to pave the way to the creation of a virtual repository of geotechnical information to be operated in the future by a consortium of local, state and federal agencies.The research will benefit the public in many ways. It will disseminate geotechnical information to the students, researchers and practitioners. It will organize geotechnical information, and improve its archival and retrieval for local, state and federal agencies, universities, and companies. It will generate an information platform for the development of large-scale geographic information systems of natural hazards such as liquefaction-induced lateral spreads during earthquakes. It will promote education and research in engineering, and stimulate data exchange and collaboration among researchers and practitioners.
