摘　　要：历次震害调查表明,工程结构的震害与场地地震反应密切相关,因此,研究场地地震反应对于工程结构的抗震设防具有重要的理论意义和实用价值。岩土竖向台阵是开展场地地震反应研究的重要平台,作为获取地表及下伏地层地震动记录的主要方法之一,为场地地震反应的研究提供了数据支撑。文中基于世界上现有多数岩土竖向台阵的分布情况,从地理位置、土层岩性、仪器布设和速度结构四方面详细介绍了美国加纳谷井下台阵、金银岛岩土台阵、日本港湾人工岛井下台阵以及中国防灾科技学院场地与结构地震观测台阵的基本信息。结合大量相关文献,总结归纳了依托岩土竖向台阵开展土体非线性动力特性、场地放大效应以及土层地震反应分析方法等研究的若干进展,展望了后续研究亟需改善的问题,对深入开展不同深度土体动力响应机理和深厚土层场地地震反应研究具有一定的参考价值。Previous seismic damage investigations have shown that the seismic damage of engineering structures is closely related to the site seismic response.Therefore,studying the site seismic response has significant theoretical and practical value for the earthquake fortification of engineering structures.The geotechnical vertical array is an important platform for conducting site seismic response studies.As one of the main methods of obtaining strong ground motion records of the surface and underlying strata,it provides data support for the study of site seismic response.Based on the distribution of most of the existing geotechnical vertical arrays in the world,this paper introduces the basic information of the Garner Valley downhole array and the Treasure Island geotechnical array in the United States,the Port Island downhole array in Japan and the seismic monitoring array of site and structure of the China Institute of Disaster Prevention in detail from four aspects:geographical location,soil layer lithology,instrument layout,and velocity structure.Combined with a large number of relevant literatures,this paper summarizes the research progress on soil nonlinear dynamic characteristics,site amplification effect,and seismic response analysis methods of soil layers utilizing geotechnical vertical array.It looks forward to the problems that urgently need to be improved in the follow-up research,which has a certain reference value for the in-depth study of the dynamic response mechanism of soil at different depths and the site seismic response with deep soil layers.
