Workshop for Geotechnical Research Needs for the Assessment and Mitigation of Infrastucture Deterioration in Response toEarthquakes

本次研讨会的目的是讨论评估和减轻强烈地面震动对基础设施造成的破坏的岩土技术研究需求。基础设施指的是交通系统、滨水结构、挡水结构（如土坝）、地下结构，以及一般情况下任何建在土壤上或用土壤建造的结构。地震造成的基础设施损失占了初始建设成本的很大一部分。评估和减轻对基础设施的损害涉及确定大地震对基础设施造成的潜在损害，以及通过改进设计和施工方法来减少这些损失所需的研究。特别关注的是这些设计和施工方法的验证。它的动机是这样的问题：如果发生8级地震，能否估计对基础设施的破坏？目前的分析方法是否足以评估大震级地震的潜在损害，并提供一种经济的方法来加强基础设施？只有验证了分析所用的程序，才能有效地回答这些问题。本次讲习班将以最近几次讲习班的成果为基础，并汇集这些讲习班的成果，这些讲习班讨论了这一更广泛的减轻地震灾害倡议的特定方面。会议将于1992年2月4日至5日在加州大学戴维斯分校举行。

The aim of this workshop is to discuss the geotechnical research needs for the assessment and mitigation of damage to the infrastructure resulting from strong ground shaking. Infrastructure refers to transportation systems, waterfront structures, water retaining structures such as earth dams, underground structures, and in general, any structure built on or of soils. Losses in the infrastructure due to earthquake damage has been a significant fraction of the initial construction costs. Assessment and mitigation of damage to the infrastructure involves identifying the potential damage to the infrastructure caused by large earthquakes, as well as the research needed to reduce these losses through improved design and construction methods. A particular focus is on verification of these design and construction methods. It is motivated by questions such as: In the event of a magnitude 8 earthquake occurring, can an estimate be made of the damage to the infrastructure? Are the current methods of analysis adequate to evaluate the potential damage due to a large magnitude earthquake and to provide an economic method for strengthening the infrastructure? These questions can be answered effectively only if the procedures used for analysis have been verified. This workshop will build upon, and bring together, the results from recent workshops which addressed particular aspects of this broader earthquake hazard mitigation initiative. It will be held on February 4-5, 1992 at the University of California at Davis.
