CMS-0219463 PI：Jean-Pierre Bardet机构：南加州大学标题：“ITR解决方案用于交换和利用岩土工程信息“岩土工程信息描述了上部土壤沉积物的特性（通常深至50米），我们的大部分民用基础设施（例如，建筑物、道路、桥梁、机场、港口和工厂）。 每年，大量的岩土工程信息产生的巨大努力和费用的项目，包括那些由国家科学基金会（NSF），以及许多其他地方，州，和联邦机构赞助的进行。 这些项目的数据和结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，因此往往难以甚至不可能仔细检查、修订和应用数据。 1998年在南加州大学（USC）举行的NSF研讨会明确地在研究人员和从业人员之间建立了更好地交流岩土工程信息的一致共识。 如今，信息技术（IT）为收集、交换和利用岩土工程信息提供了新的强大机会，为了我们的民用基础设施，应该对其进行探索。我们的研究利用了自1998年以来在南加州大学开展的几个IT项目中获得的最新经验，创建了解决与收集相关的主要问题的ITR方法，岩土工程信息的交流与利用。 该研究整合了不同的IT方法，以全面完整地描述和利用岩土工程信息，从实验室和现场的数据生成到土木基础设施系统中的工程师和规划师的最终使用。 本研究的具体目标是：1.根据领域专家对选定岩土工程信息的知识定义通用数据结构。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。开发岩土工程信息的数据挖掘工具，并创建集成数据和元数据的QA/QC算法。 这项研究关注的是IT方法的发展，使岩土工程信息可用于那些参与规划，设计，建设和维护我们的民用基础设施系统。 在研究过程中开发的工具和方法将在五个研究合作者的实际工作环境中进行测试，即加州交通部（Caltranss），洛杉矶水电部（LADWP），加州地质调查局（CGS），法国地质矿产研究局（BRGM）和日本科比大学。 预计本研究中提出的信息技术概念将有助于为将来由地方、州和联邦机构组成的联合体运作的岩土工程信息虚拟存储库的建立铺平道路。 它将向学生、研究人员和从业人员传播岩土工程信息。 它将组织岩土工程信息，并为地方、州和联邦机构、大学和公司改进其存档和检索。 它将建立一个信息平台，用于开发大规模的自然灾害地理信息系统，例如地震期间断层引起的横向扩展。 它将促进工程方面的教育和研究，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.
