项目摘要

This research program is part of the initiative to collect perishable data resulting from the 17 October 1989 Northern California (Loma Prieta) earthquake. The objective is to obtain data on the performance of five soil nailed walls in the San Francisco Bay area during the Loma Prieta earthquake. This perishable data will be compared at a later time with the pre- earthquake measurements on the same walls, in order to evaluate the performance of soil nailed walls under seismic conditions. Soil nailing is a construction procedure used to shore vertical soil cuts for temporary or permanent purposes. Related procedures included conventional soldier pile and tie- back systems. Because of the uncertainties involved with the design of soil nailed walls, building officials have expressed concern regarding soil nailing (Engineering News Record, October 5, 1898). As a result, Professor Felio was appointed Chairman of the American Society of Civil Engineers-Los Angeles Section Task Committee on Soil Nailing in order to establish design, construction, and monitoring guidelines for the City of Los Angeles. This committee has been collecting information on the subject as well as contacting researchers, constructors, and designers in the United States for information. The survey is being supervised by Professor Felio and Mr. Pirooz Barar of Pirooz Barar and Associates, San Francisco, a soil nailing designer in California with experience in supervising the construction of soil nailed walls in San Francisco, Oakland, and the Los Angeles area.

该研究计划是收集 1989 年 10 月 17 日北加州（洛马普里埃塔）地震产生的易腐烂数据计划的一部分。目的是获取洛马普列塔地震期间旧金山湾地区五座土钉墙的性能数据。这些易腐烂的数据稍后将与同一墙体的震前测量结果进行比较，以评估土钉墙在地震条件下的性能。土钉是一种用于临时或永久目的固定垂直土壤切口的施工程序。相关程序包括传统的士兵桩和回接系统。由于土钉墙设计存在不确定性，建筑官员对土钉墙表示了担忧（《工程新闻记录》，1898 年 10 月 5 日）。因此，费利奥教授被任命为美国土木工程师学会洛杉矶分会土钉工程委员会主席，以便为洛杉矶市制定设计、施工和监测指南。该委员会一直在收集有关该主题的信息，并联系美国的研究人员、施工人员和设计师以获取信息。这项调查由旧金山 Pirooz Barar and Associates 的 Felio 教授和 Pirooz Barar 先生监督，他们是加利福尼亚州的土钉设计师，在监督旧金山、奥克兰和洛杉矶地区土钉墙的施工方面拥有丰富的经验。
