| 摘 要： | 在过去的20年里，近场问题受到了地震学家和土木工程师的共同关注，一方面原因旨在阐明地震本身的机理，解释新现象；另一方面是由于地震动作为一种主要的输入荷载，在某些情况下将对整个结构设计的最终结果起到控制作用. 同时试验和评估等其它领域的相关研究也均以指定的荷载形式为前提，荷载形式的变化直接影响了土木工程中的诸多方面，所以希望研究这种荷载的规律并获得其与结构反应之间的关系. 本文回顾了近场问题研究的历史，介绍了近年来国内外针对近场地震动所展开的相关研究工作，其中包括近场地震动本身的特性与近场地震动对土木工程结构的影响等方面，指出了目前存在的问题和进一步应该研究的方向，对于近场问题的深入研究具有一定的参考价值.

| Abstract: | In the last twenty years, near-field problems became an important topic for both seismologists and civil engineers. The one aspect is to illuminate mechanisms of earthquakes and explain new phenomena. The another aspect is the ground motions, which are usually assigned by engineers as a type of input load for seismic design of structures, sometimes can control the final design results. The experiments, performance evaluations and other related aspects are all based on the specified type of load. As a result, many aspects related to civil engineering will be influenced by changes of the type of load. Hence, the characteristics of the load and the corresponding response of structures are desired for studying. In this paper, the state-of-the-art of near-field problems in civil engineering is comprehensively reviewed, which include inherent characteristics of near-field ground motions and influences of these ground motions on civil structures. The existing problems are pointed out and work needed to be further investigated in the future is suggested. It is believed that the information in this paper can be useful to advance the state of investigation on near-field problems. |
