摘要

2015年4月25日至5月12日，尼泊尔中北部发生一系列大地震，不仅造成大量人员伤亡，还对建筑结构和基础设施造成严重破坏。到目前为止，大多数关于这一事件的地震勘测研究都将结构损坏和生命损失归因于尼泊尔建筑设计规范的相对宽松执行，因为大多数损坏的结构大多是业主建造的。基于相当有限的地震动数据，本文研究了尼泊尔地震序列的基本特征。值得强调的是，脉冲状特征在软场地和岩石场地都很显著，这也是除场地效应之外的主要冲击地面运动的独特特征的原因。

Ground motion characteristics of the 2015 Gorkha earthquake sequence

On 25 April - 12 May 2015, a series of large earthquakes struck the north-central part of Nepal, causing not only a substantial number of casualties, but also heavy damage to the building structures and infrastructure facilities. Up to now, most of seismic reconnaissance studies about this event have attributed the structural damage and life losses to the relatively loose implementation of the building design codes in Nepal, as most of those damaged structures were largely owner-built. Based on the quite limited ground motion data, this paper investigated the primary characteristics of the Nepal earthquake sequence. It is highlighted that the pulse-like features are significant at both the soft and rock sites, which is also responsible for the unique characteristics of the main-shock ground motions other than site effects.

期刊介绍： The Earthquakes and Structures, An International Journal, focuses on the effects of earthquakes on civil engineering structures. The journal will serve as a powerful repository of technical information and will provide a highimpact publication platform for the global community of researchers in the traditional, as well as emerging, subdisciplines of the broader earthquake engineering field. Specifically, some of the major topics covered by the Journal include: .. characterization of strong ground motions, .. quantification of earthquake demand and structural capacity, .. design of earthquake resistant structures and foundations, .. experimental and computational methods, .. seismic regulations and building codes, .. seismic hazard assessment, .. seismic risk mitigation, .. site effects and soil-structure interaction, .. assessment, repair and strengthening of existing structures, including historic structures and monuments, and .. emerging technologies including passive control technologies, structural monitoring systems, and cyberinfrastructure tools for seismic data management, experimental applications, early warning and response
