Planning for Site Selection, Installation and Operation of Geotechnical Strong-Motion Arrays

这项行动是为了支持两个研讨会，它们将共同解决岩土工程场地的地震强震阵列问题。具体来说，他们将记录当前和计划的阵列；为岩土工程场地制定未来强运动仪器的战略计划；并制定长期实施计划和管理架构。讲习班的参加者将来自美国和其他正在进行重大岩土工程强震监测的国家。在地表和地下部署强震仪器进行岩土监测，在直接测量地表地质影响方面取得了重大进展。钻孔测量为解释地表观测和理解场地地质非线性应力-应变行为（包括土壤破坏）的方法提供了关键约束。井眼测量提供的数据可以解决一些最基本的尚未解决的地震学和地震工程问题，包括非线性行为开始的动态应变阈值，以及对应变限制的地面运动的见解。由于获得所需的测量是昂贵的，为了在合理的时间内最大限度地获得有用记录的可能性，计划和广泛协调监测方案和倡议是非常重要的。第一次讲习班将记录目前的监测活动，并为今后的监测制定战略计划。第二次研讨会将制定协调岩土工程强运动监测的长期实施和管理结构。研讨会的报告将：(1)记录当前的岩土强震监测；(1)提供未来监测的战略计划、未来监测的实施计划、未来监测的协调与管理计划。这两个研讨会的论文集将由强运动观测系统组织联合会（COSMOS）出版，并将以光盘形式分发。会议记录也将发布在COSMOS主页http://www.cosmos-eq.org上

This action is to support two workshops which, together, will address earthquake strong-motion arrays for geotechnical engineering sites. Specifically, they will document current and planned arrays; develop a strategic plan for future strong motion instrumentation for geotechnical sites; and develop a long-term implementation plan and management structure. The workshop participants will be from the United States and other countries where significant geotechnical strong-motion monitoring is being conducted.The deployment of strong-motion instruments at the surface and in the subsurface for geotechnical monitoring provides a major advance in the direct measurement of the effects of surface geology. Borehole measurements provide critical constraints on methods for interpreting surface observations and for understanding non-linear stress- strain behavior of site geology up to and including soil failure. Borehole measurements provide data to address some of the most basic unresolved seismological and earthquake engineering issues, including the dynamic strain threshold where non- linear behavior begins, with insights into strain-limited ground motions. Because the required measurements are costly to obtain, planning and broad coordination of monitoring programs and initiatives is highly important in order to maximize the likelihood of obtaining useful recordings in a reasonable time period.The first workshop will document the current monitoring activities, and develop a strategic plan for future monitoring. The second workshop will develop a long-range implementation and management structure for coordinated geotechnical strong-motion monitoring. The report from the workshop will: (1) document the current geotechnical strong-motion monitoring; (1) provide a strategic plan for future monitoring, an implementation plan for future monitoring, and a coordination and management plan for future monitoring. The Proceedings of the two workshops will be published by the Consortium of Organizations for Strong Motion Observation Systems (COSMOS) and will be distributed on CD-ROM. The proceedings also will be posted on the COSMOS Home Page, http://www.cosmos-eq.org
